TOTIPALMATE SWIMMERS. Order IV. STEGANOPODES

TROPIC BIRDS. Family PHAETHONTIDAE

Tropic Birds are Tern-like birds, having all the toes connected by a web, and having the two central tail feathers very much lengthened.

112. Yellow-billed Tropic Bird. Phæthon americanus.

Range.--Tropical regions, breeding in the Bahamas, West Indies and the Bermudas, casual in Florida and along the South Atlantic coast.

The Tropic Birds are the most strikingly beautiful of all the sea birds; they are about 30 inches in length, of which their long slender tail takes about 20 inches. They fly with the ease and grace of a Tern, but with quicker wing beats. They feed on small fish, which they capture by darting down upon, and upon snails which they get from the beach and ledges. They build their nests in the crevices and along the ledges of the rocky cliffs. While gregarious to a certain extent they are not nearly as much so as the Terns. The nest is made of a mass of seaweed and weeds; but one egg is laid, this being of a creamy or pale purplish ground color, dotted and sprinkled with chestnut, so thickly as to often obscure the ground color. Size 2.10 × 1.45. Data.--Coney Is., Bermudas, May 1, 1901. Nest made of moss and seaweed in a crevice on ledge of cliff. Collector, A. H. Verrill.

113. Red-billed Tropic Bird. Phæthon æthereus.

Range.--Tropical seas, chiefly in the Pacific Ocean; north to southern California.

They breed on several islands in the Gulf of California. This species differs from the preceding in having a red bill, and the back being barred with black. Their plumage has a peculiar satiny appearance and is quite dazzling when viewed in the sunlight. They are strong fliers and are met with, hundreds of miles from land. They often rest upon the water, elevating their long tails to keep them from getting wet. They nest, as do the preceding species, on rocky islands and are said to also build their nests in trees or upon the ground. The single egg that they lay has a creamy ground and is minutely dotted with chestnut. Size 2.40 × 1.55. Data.--Daphone Is., Galapagos Is., South Pacific, March 6, 1901. Egg laid in hole of a sea cliff. The eggs are easily told from those of the yellow-billed by their much larger size. Collector, R. H. Beck.

113.1 Red-tailed Tropic Bird. Phæthon rubricaudus.

Range.--Tropical regions of the Pacific and Indian Oceans, accidental off the coast of Lower California.

This is a singularly beautiful species resembling the latter except that the central tail feathers are bright red, with the extreme tips white. During August and September they breed in large colonies on small islands in the South Seas. On Mauritius Island they build their nests either in the trees or place them on the ground; the nest is made of seaweed, sticks and weeds; numbers of them nest on Laysan Is., of the Hawaiian group, concealing their nests on the ground under overhanging brush.

The single egg has a pale purplish ground speckled with brown.

GANNETS. Family SULIDAE

Gannets are large stoutly built birds, having the four toes joined by a web; they have a small naked pouch beneath the bill; the bill is a little longer than the head, and the tail is quite short. The plumage of the adults is generally white, that of the young grayish.

114. Blue-faced Booby. Sula syanops.

Range.--Widely distributed in the tropical seas, north casually to Florida and breeding in the Bahamas.

Like the rest of the Gannets, this one is stupid and will often remain on the nest until removed with the hand, merely hissing at the intruder. Often they lay their eggs on the bare ground, but sometimes the nest is lined with seaweed or grass. They lay either one or two eggs early in April. These eggs are of a dull white color and are heavily covered with a chalky deposit. Size 2.50 × 1.70. Data.--Clarion Is., Mexico, May 24, 1897. Nest a mere hollow in the sand near the beach. Collector, A. W. Anthony.

114.1. Blue-footed Booby. Sula nebouxi.

Range.--Pacific coasts and islands from the Gulf of California southward to Chili.

These birds nest in numbers on the island of San Pedro Martir in the Gulf of California. They lay but a single egg, placing it upon the bare rock. Their breeding season extends from the latter part of March into May. The egg is a dull white, generally nest stained and is covered with the usual chalky deposit. Size 2.35 × 1.60. Data.--Clarion Island, Mexico, May 21, 1897. Two eggs in a hollow in the sand near the beach. Collector, A. W. Anthony.

115. Booby. Sula leucogastra.

Range.--Tropical coasts and islands of the Atlantic; north casually to Georgia.

The common Booby is an abundant bird on some of the islands of the Bahamas and Bermudas; it is commonly called the Brown Booby because the upper parts are of a brownish gray. These birds, as do the other Gannets, have great powers of flight and without apparent effort dart about with the speed of an arrow. They are quite awkward upon their feet and are not very proficient swimmers. They rarely rest upon the water except when tired. Hundreds and sometimes thousands of them breed in company, laying their eggs upon the bare rocks. Sometimes a few sticks or grasses will be placed about the bird to prevent the eggs from rolling away. They generally lay two eggs, chalky white and nest stained. Size 2.40 × 1.60. Data.--Key West, Bahamas, April 14, 1891. No nest; two eggs laid on the bare rocks.

115.1. Brewster's Booby. Sula brewsteri.

Range.--Pacific coast from Lower California southward. This Gannet replaces the common Booby on the Pacific coast. It nests abundantly on many islands in the Gulf of California, and in company with the blue-footed variety, on San Pedro Martir Island. They generally lay two eggs, placing them upon the bare rocks and surrounding them with a ring of sticks and seaweed to keep them in place. The eggs are chalky white and cannot be distinguished from those of the other Boobies. Data.--San Benedicto Is., Lower California, May 18, 1897. Single egg laid on the sand amid a few blades of grass.

116. Red-footed Booby. Sula piscator.

This is another species that is only occasionally taken on the Florida coast. The habits of the birds and their nesting habits are the same as those of the others of the family. Two chalky white eggs are laid. Data.--San Benedicto Is., Lower California, May 18, 1897. Single egg. Nest a few twigs of rank grass. Collector, A. W. Anthony.

117. Gannet. Sula bassana.

Range.--North Atlantic, breeding, in America, only on Bird Rocks in the St. Lawrence.

These are the largest of the family, being 35 inches in length. They feed on fish which they catch by diving upon, from the air. When flying their neck is carried fully extended. They rest on the water when tired, the numerous air cells beneath the skin, causing them to sit high up in the water and enabling them to weather the severest storm in perfect safety. The only known breeding place in America is Bird Rocks, where they nest by thousands, placing their nests in rows on the narrow ledges; the nests are made of piles of seaweed, mud and stones. They lay but one egg of dingy white color and covered with a chalky deposit. On St. Kilda Island, off the coast of Scotland, they breed by millions. They are very tame and will frequently allow themselves to be touched with the hand. It is said that thousands of the young are killed by fishermen every year and marketed in Edinburg and other places. Data.--St. Kilda Island, Scotland, June 18, 1896. Single egg laid on a large mass of seaweed on a sea cliff. Collector, H. McDonald.

DARTERS. Family ANHINGIDAE

118. Water Turkey. Anhinga anhinga.

Range.--Tropical America, north to the South Atlantic States and up the Mississippi Valley to Illinois.

Anhingas or Snake Birds are curiously formed creatures with a Heron-like head and neck, and the body of a Cormorant. They live in colonies in inaccessible swamps. Owing to their thin and light bodies, they are remarkable swimmers, and pursue and catch fish under water with ease. When alarmed they have a habit of sinking their body below water, leaving only their head and neck visible, thereby having the appearance of a water snake. They also fly well and dive from their perch into the water with the greatest celerity.

They nest in colonies in the swamps, placing their nests of sticks, leaves and moss in the bushes over the water. They breed in April, laying from three to five bluish eggs, covered with a chalky deposit. Size 2.25 × 1.35. Data.--Gainesville, Florida, May 18, 1894. Nest in the top of a button-wood tree, made of leaves and branches, overhanging the water. Collector, George Graham.

PELICAN POND.
Washington Zoological Park.

CORMORANTS. Family PHALACROCORACIDÆ

Cormorants have a more bulky body than do the Anhingas; their tail is shorter and the bill strongly hooked at the tip. Cormorants are found in nearly all quarters of the globe. They are very gregarious and most species are maritime. They feed upon fish which they catch by pursuing under water. Most of the Cormorants have green eyes.

119. Cormorant. Phalacrocorax carbo.

Range.--The Atlantic coast breeding from Maine to Greenland.

The common Cormorant or Shag is one of the largest of the race, having a length of 36 inches.

In breeding plumage, the black head and neck are so thickly covered with the slender white plumes as to almost wholly obscure the black.

There is also a large white patch on the flanks. They nest in colonies on the rocky shores of Newfoundland and Labrador, placing their nests of sticks and seaweed in rows along the high ledges, where they sit, as one writer aptly expresses it, like so many black bottles. A few pairs also nest on some of the isolated rocky islets off the Maine coast. During the latter part of May and during June they lay generally four or five greenish white, chalky looking eggs. Size 2.50 × 1.40. Data.--Black Horse Rock, Maine coast, June 6, 1893. Four eggs in a nest of seaweed and a few sticks; on a high ledge of rock. Collector, C. A. Reed.

120. Double-crested Cormorant. Phalacrocorax auritus auritus.

Range.--The Atlantic coast and also in the interior, breeding from Nova Scotia and North Dakota northward.

This is a slightly smaller bird than carbo, and in the nesting season the white plumes of the latter are replaced by tufts of black and white feathers from above each eye. On the coast they nest the same as carbo and in company with them on rocky islands. In the interior they place their nests on the ground or occasionally in low trees on islands in the lakes. They breed in large colonies, making the nests of sticks and weeds and lay three or four eggs like those of the common Cormorant but averaging shorter. Size 2.30 × 1.40. Data.--Stump Lake, North Dakota, May 31, 1897. Nest of dead weeds on an island. Six eggs. Collector, T. F. Eastgate.

NESTS OF DOUBLE-CRESTED CORMORANTS.

120a. Florida Cormorant. Phalacrocorax auritus floridanus.

This sub-species is a common breeding bird in the swamps and islands of the Gulf coast and north to South Carolina and southern Illinois. The nests are placed in the mangroves in some of the most impenetrable swamps and are composed of twigs and lined with leaves or moss. They lay three or four chalky bluish white eggs. Size 2.30 × 1.40. Data.--Bird Is., Lake Kissimee, Florida, April 5, 1898. Three eggs. Nest made of weeds and grass, in a willow bush.

120b. White-crested Cormorant. Phalacrocorax auritus cincinatus.

Range.--Northwestern coast of North America, breeding in Alaska, and south to the northern boundary of the United States, breeding both in the interior and on the coast, in the former case generally on the ground or in low trees on swampy islands and in the latter, on the rocky cliffs of the coasts and islands. The nests are built in the same fashion as the other Cormorants, and the three to five eggs are similar. Size 2.45 × 1.40.

120c. Farallon Cormorant. Phalacrocorax auritus albociliatus.

Range.--This sub-species breeds on the coasts and islands of California and southward.

In company with other species of Cormorants, these birds breed in large numbers on the Farallones, placing their nests well up on the higher ridges and rocks. They breed most abundantly during May. When nesting on the inland islands, they place their nests in low bushes. Their nests and eggs are similar to those of the other Cormorants. Size 2.40 × 1.50. Data.--Farallones, California. Nest of weeds and seaweed on the rocks. Collector, W. O. Emerson.

121. Mexican Cormorant. Phalacrocorax vigua mexicanus.

Range.--Breeds abundantly from southern Texas, south through Mexico; north rarely to Kansas; has recently been found breeding in limited number on some of the Bahamas. In the interior they nest in trees, chiefly those overhanging or growing in the water. On the coasts they nest on the rocky ledges, as do the other Cormorants. They nest in colonies building their abode of twigs and weeds, and during May laying three or four eggs, greenish white in color and chalky, as are all the Cormorants. Size 2.25 × 1.35.

122. Brandt's Cormorant. Phalacrocorax penicillatus.

Range.--Pacific coast breeding along the whole coast of the United States.

This species is found more abundantly on the Farallones than is the Farallone Cormorant. Like the other Cormorants breeding on these islands, these cling closely to their nests, for fear of being robbed by the Gulls, that are ever on the watch to steal either eggs or young. Their nesting habits and eggs are identical with those of the other species. Size 2.50 × 1.50. Data.--Bird Island, California, May 24, 1885. A very bulky nest of seaweed on the rocks. Collector, A. M. Ingersoll.

123. Pelagic Cormorant. Phalacrocorax pelagicus pelagicus.

Range.--Coast of Alaska.

These are perhaps the most beautiful species of Cormorants, having brilliant violet green metallic reflections and, in the breeding plumage, crests on the forehead and nape, as well as large white flank patches. They breed in large colonies on the Aleutian Islands, placing their nests of sticks and sea mosses on the rocky ledges, often hundreds of feet above the sea level. Three or four eggs are laid during May and June. The young birds when hatched are naked and black, and are repulsive looking objects, as are those of all the other Cormorants. The eggs are greenish white with the usual calcareous deposit. Size 2.30 × 1.40.

123a. Violet-green Cormorant. Phalacrocorax pelagicus robustus.

This sub-species is found on the Pacific coast from Washington to the Aleutian Islands. Their habits and nests and eggs are the same as those of the Pelagic Cormorant, nesting on the high cliffs of the rocky islands. The eggs are the same size as those of the preceding.

123b. Baird's Cormorant. Phalacrocorax pelagicus resplendens.

This variety breeds on the Pacific coast from Washington south to Mexico. They nest on the Farallones, but in smaller numbers than the other varieties found there. Both the birds and their eggs are smaller than the preceding. Size of eggs 2.20 × 1.40.

124. Red-faced Cormorant. Phalacrocorax urile.

Range.--Southwest coast of Alaska, migrating to Japan in the winter.

This species differs from the Pelagic chiefly in having the forehead bare. They do not differ in their breeding habits from others of the family. That the Cormorants are expert fishermen may be seen from the fact that the Chinese tame and have them catch fish for them, placing a ring around their neck to prevent their swallowing the fish. Their nesting places are very filthy, being covered with excrement and remains of fish that are strewn around the nests. They breed in June laying three or four eggs. Size 2.50 × 1.50.

PELICANS. Family PELECANIDÆ

Pelicans are large, short legged, web footed (all four toes joined by a web) birds, the most noticeable feature of which is the long bill with its enormous pouch suspended from lower mandible. This pouch, while normally contracted, is capable of being distended to hold several quarts. It is used as a scoop in which to catch small fish. Their skin is filled with numerous air cells, making them very light and buoyant.

125. American White Pelican. Pelecanus erythrorhynchos.

Range.--Temperate North America, breeding in the interior, from Utah and the Dakotas northward. These large birds, reaching a length of five feet, are entirely white except for the black primaries. They get their food by approaching a school of small fish and, suddenly dipping their head beneath the surface, sometimes scoop up a large number of fish at a time; after allowing the water to run out of the sides of the mouth, they proceed to swallow their catch. They nest in large communities on islands in some of the inland lakes.

Great Salt Lake, Utah, and Shoal Lake, Manitoba, furnish breeding ground for many thousands of Pelicans. They build their simple nests on the ground, making them of sticks and weeds. They generally lay two eggs, but often three or four. Size 3.45 × 2.30. Data.--Egg Island, Great Salt Lake, June 19, 1884. Two eggs. Nest a slight hollow in the ground, surrounded by a few sticks. Collector, F. F. Leonard.

Chalky white.

AMERICAN WHITE PELICAN.

126. Brown Pelican. Pelecanus occidentalis.

Range.--Found on the South Atlantic and Gulf coasts of the United States.

Brown Pelicans are about 50 inches in length; they have a blackish and grayish body and a white head and neck with a brown stripe down the back of the latter. The pouch is a dark greenish brown. This species is maritime and is not found inland. They breed in large colonies on many of the islands in the Gulf of Mexico and on Pelican Island on the east coast of Florida, in which latter place they are now protected from further depredations at the hand of eggers and gunners.

Their fishing tactics differ from those of the White Pelican. They dive down upon the school of fish from the air and rarely miss making a good catch. Their nests are quite bulky structures made of sticks and weeds and grasses. These are generally located on the ground but occasionally in low mangroves, these latter nests being more bulky than the ground ones. They lay from two to five chalky white eggs during May and June. Size 3. × 1.90. Data.--Tampa Bay, Fla., May 29, 1894. Three eggs. Nest in the top of a stout mangrove; made of sticks, branches and leaves. Collector, Geo. Graham.

127. California Brown Pelican. Pelecanus californicus.

Range.--Pacific coast from British Columbia south to the Galapagos Islands.

This bird is similar to the preceding, but larger and the pouch is reddish. They breed abundantly on the Coronado Islands and southward. Their habits, nesting habits and eggs are the same as those of the Brown Pelican. Size of the three or four chalky white eggs is 3.10 × 1.95. Data.--Coronado Islands, Calif., March 28, 1897. Three eggs. Nest of sticks, lined with green leaves, located on the ground. Collector, H. McConville.

MAN-O'-WAR BIRDS. Family FREGATIDÆ

128. Man-o'-war Bird. Fregata aquila.

Range.--Tropical seas, north regularly in America to the South Atlantic and Gulf coasts, casually farther.

Man-o'-war Birds or "Frigates," as they are often called, are remarkable birds in many respects. In comparison with their weight they have the largest expanse of wing of any known bird. Weighing only about four pounds they have an extent of from seven to eight feet, their wings being extremely long and pointed.

The length of the bird is about 40 inches, of which the tail comprises about 18 in., 10 inches of this being forked. They have a large bright orange gular sac, a long, hooked bill, and small slightly webbed feet. Their powers of flight combine the strength of the Albatrosses and the grace of the Terns. They are very poor swimmers and do not dive, so are forced to procure their food by preying upon the Gulls and Cormorants, forcing them to drop their fish, which the pirates catch before it reaches the water. They also feed upon flying fish, catching them in the air, whither they have been driven by their enemies in their natural element. They nest in large colonies on some of the Bahama Islands and on some of the small Florida Keys. Their nests are small frail platforms of sticks and twigs and the single egg is laid in March and April. It is white and has a smooth surface. Size 2.80 × 1.90. Data.--Key Verde, Bahamas, March 6, 1889. Single egg. Nest a frail affair of sticks on a cactus. Collector, D. P. Ingraham.

Order V. ANSERES

DUCKS, GEESE AND SWANS. Family ANATIDAE

The birds comprising this family are of greatly varying sizes, but all have webbed feet, and generally the bill is broader than high, and is serrated on the edges or provided with gutters to act as a strainer in assisting the birds to gather their food.

129. Merganser. Mergus americanus.

Range.--North America, breeding from the northern border of the United States northward.

The three species of Mergansers are almost exclusively fish eating birds. Therefore their flesh is unpalatable and they are known as "Fish Ducks."

They are also sometimes called "Sawbills" because of the teeth-like serration on both the upper and the under mandibles. Unlike the other species of ducks, their bills are long, slender and rounded instead of being broad and flat; it is also hooked at the tip. Like the Cormorants, they often pursue and catch fish under the water, their teeth-like bills enabling them to firmly hold their prey.

The American Mergansers, Goosanders, or Sheldrakes, as they are often called, are found both on the coast and in the interior. Except in certain mountainous regions, they breed chiefly north of the United States. The male bird has no crest and the head is a beautiful green, while the female has a reddish brown crest and head, shading to white on the chin. They build their nest in hollow trees near the water. It is made of grasses, leaves and moss and is lined with feathers from the breast of the female. During May, they lay from six to ten eggs of a creamy or buff color. Size 2.70 × 1.75. Data.--Gun Is., Lake Winnipeg. June 16, 1903. Eleven eggs in a nest of white down, located between two large boulders. Collector, Walter Raine.

130. Red-breasted Merganser. Mergus serrator.

Range.--North America, breeding from northern United States northward.

This species is more abundant than the preceding. It is slightly smaller, being 22 inches in length, and the male is crested. Found abundantly in the United States in winter. Breeds commonly in the interior of British America and in Labrador and Newfoundland. They make their nests on the ground, near the water, concealing them under rocks or tufts of grass. The nest is made of grasses, leaves and moss and lined with feathers. They lay, generally, about ten eggs of a buffy or greenish buff color. Size 2.50 × 1.70. Data.--Lake Manitoba, N. W. Canada. Two eggs in a hollow lined with down, under a patch of rose bushes near shore. Collector, Jos. Hamaugh.

131. Hooded Merganser. Lophodytes cucullatus.

Range.--North America, breeding locally throughout its range, in the interior. These are beautiful little Ducks distinguished from all others by the semi-circular, compressed crest which is black with an enclosed white area. They make their nests in hollow trees, in wooded districts near the water, lining the cavity with grasses and down. They lay ten or twelve grayish white eggs. Size 2.15 × 1.70.

132. Mallard. Anas platyrhynchos.

Range.--Northern Hemisphere, breeding in America from northern United States northward, and wintering south to Panama and the West Indies.

Contrasting with the preceding Fish Ducks, the Mallards are regarded as one of the most esteemed table birds. They feed on mollusks and marine insects which they generally reach by tipping in shallow water. They nest in many localities in the United States but more abundantly north of our borders. They nest in fields in close proximity to ponds or lakes, placing their nests of grasses and feathers in the tall grass. In May and June they lay from six to ten eggs of a buffy or olive color. Size 2.25 × 1.25. Data.--San Diego, California, May 19, 1897. Nest made of grass, lined with down, placed on the edge of a field near a pond.

NEST AND EGGS OF AMERICAN MERGANSER.

This species usually nest in holes in trees, but on this island
they were nesting in holes under boulders.

133. Black Duck. Anas rubripes.

Range.--Eastern North America, breeding from the middle portions north to the Hudson Bay territory and Labrador.

Throughout their breeding region, one or more pairs of these ducks nest in nearly every favorable locality. Their nests are placed on the ground in marshes, swamps or fields bordering a pond or lake, the nest being concealed in the long grass or reeds. They breed in equal abundance, either in the interior or along the sea coast; in the latter case their nests are often placed beside of, or under an overhanging rock. It is made of weeds, grass and moss and is lined with feathers and down. They lay from six to twelve eggs during May and June; these are buff or greenish buff in color. Size 2.30 × 1.70. Data.--Duck Is., Maine, June 3, 1893. Nest of grasses, concealed in a large tuft on water's edge.

134. Florida Duck. Anas fulvigula fulvigula.

Range.--Florida and the Gulf of the Mississippi.

This is a similar, lighter colored, locally distributed race of the foregoing. The most noticeable difference in plumage between this and the Black Duck is the absence of markings on the chin. The habits are the same, and the eggs, which are deposited in April, are similar to those of the Black Duck, but smaller. Size 2.15 × 1.60.

134a. Mottled Duck. Anas fulvigula maculosa.

Range.--Gulf coast of Texas and up the Mississippi Valley to Kansas.

The habits of this bird differ in no way from the preceding ones. The six to ten eggs are greenish buff in color. Size 2.15 × 1.55.

135. Gadwall. Chaulelasmus streperus.

Range.--Northern Hemisphere, breeding in America, chiefly in the United States and north to Manitoba, chiefly in the interior.

South in winter to the Gulf. The males of these birds may be identified by the white speculum and the chestnut wing coverts. Gadwalls nest on the ground among the reeds of marshes or in the long grass of bordering fields; they make little or no nest but line the cavity with down from their breasts. They lay from seven to twelve eggs of a creamy buff color. Size 2.10 × 1.60. Data.--Benson Co., North Dakota, June 19, 1898. Eight eggs. Nest on the ground among rank grass on a low island in Devils Lake. Made of weeds lined with down. Collector, E. S. Rolfe.

136. Widgeon. Mareca penelope.

Range.--Northern Hemisphere, breeding in America, only in the Aleutian Islands; rare or accidental in other parts of the country.

The European Widgeon is similar in build and plumage to the following species, except that the whole head, with the exception of the white crown, is chestnut. They build their nests in the rushes, making them of reeds and grass and lining them with feathers. They lay from six to ten light buff colored eggs. Size 2.20 × 1.50.

137. Baldpate. Mareca americana.

Range.--North America, breeding in the interior from Texas north to Hudson Bay.

The Baldpate (so-called because of the white crown) or American Widgeon is a handsomely marked bird and is regarded as a great table delicacy.

The male birds cannot be mistaken for any other species because of the white crown, wing coverts and underparts and the broad green stripe, back of the eye. They breed locally in many parts of the country, building their nests of grass and weeds, neatly lined with feathers, on the ground in marshes. They lay from six to twelve creamy eggs. Size 2.15 × 1.50. Data.--Lac Aux Morts, North Dakota. Eight eggs. Nest of grass and down on ground in a grassy meadow. Collector, E. S. Bryant.

138. European Teal. Nettion crecca.

An old world species that is casually found on both coasts of America.

139. Green-winged Teal. Nettion carolinense.

Range.--Whole of North America, breeding chiefly north of the United States.

A small, handsome species, the male of which can readily be identified by the reddish brown head and neck, with the large green patch behind each ear; length fourteen inches. Green-winged Teals are our smallest representative of the Duck family. They are eagerly sought by sportsmen, both because of their beauty and the excellence of their flesh. They are among the most common of Ducks in the interior, where they nest generally in tufts of grass along ponds, lakes or brooks. Nest of grass and weeds, lined with down from the bird. Eggs buffy, four to ten in number. Size 1.85 × 1.25.

140. Blue-winged Teal. Querquedula discors.

Range.--North America, breeding from northern United States northward; rare on the Pacific coast.

Another small species, known by the blue wing coverts and the white crescent in front of eye. They nest in the same localities with the preceding species, placing their nest of grass and weeds on the ground in meadows near water. Eggs buffy white. Six to twelve in number. Size 1.90 × 1.30.

141. Cinnamon Teal. Querquedula cyanoptera.

Range.--Western United States, chiefly west of the Rocky Mountains. Casually east to Texas, Illinois and British Columbia.

The Cinnamon Teal is another small Duck, marked by the uniform rich chestnut plumage and light blue wing coverts. The speculum is green. The nesting habits are the same as those of the Teals, the nests being placed on the ground in marshes or fields near water. Their nests are closely woven of grass and weeds and lined with down and feathers from the breast of the bird. The eggs are pale buff and number from six to fourteen. Size 1.85 × 1.35.

141.1. Ruddy Sheldrake. Casarca ferruginea.

This is an Old World species that has accidentally occurred in Greenland.

142. Shoveller. Spatula clypeata.

Range.--Whole of North America, breeding in the interior from Texas northward.

This strikingly marked Duck is twenty inches in length, has a green head and speculum, blue wing coverts and chestnut belly. The bill is long and broad at the tip. It makes its nest on the ground in marshy places, of grass, weeds and feathers. Six to ten eggs constitute a complete set. They are greenish or leaden gray color. Size 2.10 x 1.50. Data.--Graham's Island, North Dakota, May 28, 1899. Nest of dead weed stems and grass, lined with down. Ten eggs. Collector, E. S. Bryant.

143. Pintail. Dafila acuta.

Range.--Northern Hemisphere, breeding in North America from northern United States northward, wintering south to Panama. This species, which is also known as the Sprig-tail, is very common in the United States in the spring and fall migrations. It is about thirty inches long, its length depending upon the development of the tail feathers, the central ones of which are long and pointed. They breed casually in many sections of the United States, but in abundance from Manitoba to the Arctic Ocean. They nest near the water, laying from six to twelve eggs of dull olive color. Size 2.20 x 1.50. Data.--Graham's Island, Devil's Lake, N. Dakota, June 15, 1900. Ten eggs. Nest on the ground, of weeds, lined with down. Colony breeding. Collector, E. S. Bryant.

144. Wood Duck Aix sponsa.

Range.--Temperate North America, breeding from Labrador and British Columbia south to Florida.

Bridal Duck is a name often given to this, the most beautiful of all Ducks.

They are beautifully marked, have a large crest, and are iridescent with all colors of the rainbow. They frequent wooded country near ponds and lakes, feeding on water insects and mollusks in the coves. They build their nests in hollow trees and stumps, often at quite a distance from the water. When the young are a few days old, they slide, scramble, or flutter down the tree trunk to the ground below, and are led to the water. The nest is made of twigs, weeds and grass, and warmly lined with down. The eggs are a buff color and number eight to fifteen. Size 2. × 1.5.

145. Rufous-crested Duck. Netta rufina.

A European species; a single specimen taken on Long Island in 1872.

146. Redhead. Marila americana.

Range.--North America at large, breeding from northern United States northward, chiefly in the interior.

A bird commonly seen in the markets where it is often sold as the following species because of their similarity. The nests are placed on the ground in marshes or sloughs, and are made of grasses, lined with feathers. Eggs from six to fourteen in number, of a buffy white color. Size 2.40 × 1.70.

WOOD DUCK.

147. Canvas-back. Marila valisineria.

Range.--Whole of North America, breeding chiefly in the interior from the United States to the Arctic Ocean.

A noted table bird, especially in the south where it feeds on wild celery. Can be distinguished from the Redhead by its darker head, lighter back, and gradually sloping bill. They nest abundantly in Manitoba, their habits being the same as the preceding. They lay from six to ten eggs of a darker shade than the Red-heads. Size 2.40 × 1.70. Data.--Haunted Lake, N. Alberta, June 12, 1897. Ten eggs. Nest of reeds in a heavy reed bed out in the lake. Collector, Walter Raine.

148. Scaup Duck. Marila marila.

Range.--North America, breeding from North Dakota northward, chiefly in the interior; south in winter to Central America.

This and the following species are widely known as "Blue-bills" owing to the slaty blue color of that member. Their plumage is black and white, somewhat similar in pattern to that of the Redhead, but darker, and the whole head is black. They nest in marshes about many of the ponds and lakes in the interior of British America. The nest is made of marsh grasses and lined with feathers. The six to ten eggs are pale grayish or greenish gray. Size 2.50 × 1.70. Data.--

Saltcoats Marshes, N. W. Canada, June 15, 1901. Ten eggs. Nest in the grass; a depression lined with down and dried grasses. Collector, Walter Raine.

149. Lesser Scaup Duck. Marila affinis.

Range.--North America, breeding from North Dakota and British Columbia northward; winters south to Central America.

This Duck is distinguished from the preceding, chiefly by its size which is about two inches less, or 17 inches in length. The nesting habits are the same as those of the Greater Scaup and the eggs are similar but smaller. Size 2.25 × 1.55. Data.--Northern Assiniboia, June 10, 1901. Ten eggs on grass and down at the edge of a lagoon. Collector, Walter Raine.

150. Ring-necked Duck. Marila collaris.

Range.--North America, breeding in the interior, from North Dakota and Washington northward. Winters from Maryland on the east and British Columbia on the west to Central America.

Similar to the Lesser Scaup in size and plumage, except that it has a narrow chestnut collar around the neck, the back is black instead of barred with white, and the speculum is gray instead of white. The habits and nesting habits of the Ring-neck do not differ from those of the other Scaups. They lay from six to twelve eggs. Size 2.25 × 1.60. Data.--Cape Bathurst, N. Y. T., June 18, 1901. Ten eggs in a slight hollow in the moss, lined with down. Collector, Captain Bodfish.

151. Golden-eye. Clangula clangula americana.

Range.--North America, breeding both on the coast and in the interior, from the northern border of the United States northward to the Arctic Ocean.

These are handsome Ducks known as "Whistlers" from the noise of their wings when flying, and "Greatheads" because of the puffy crest. The head is greenish with a large round white spot in front of, and a little below the eye. The rest of the plumage is black and white. This species nests in hollow trees near the water, lining the cavity with grass, moss and leaves, and lining the nest with down from their breasts. In May and June they lay from six to ten eggs of a grayish green color. Size 2.30 × 1.70.

152. Barrow's Golden-eye. Clangula islandica.

Range.--Northern North America, breeding north of the United States except from the mountainous portions of Colorado northward.

This Golden-eye differs from the preceding chiefly in the shape of the white spot before the eye, which in this species is in the form of a crescent. The size is the same, about 20 inches in length. The reflections on the head are purplish rather than greenish as in the preceding. The nesting habits are the same, they building in hollow trees near water. The six to ten eggs are not different from the preceding. Size 2.30 × 1.65. Data.--Alfusa, Iceland, June 30, 1900. Seven eggs. Nest of grass and down in a box attached to a tree by an islander.

153. Buffle-head. Charitonetta albeola.

Range.--North America, breeding from United States northward. Winters south to Mexico.

Gunners know this handsome little duck by the names of "Butter-ball," and "Dipper," a name also given to Grebes. It is also quite similar, but smaller (15 in. long), to the American Golden-eye but has a large white patch on the back of the head, from eye to eye. It is an active bird and, like the two preceding, is capable of diving to a great depth to get its food. Its nesting habits are like the preceding. Eggs eight to fourteen. Size 2 × 1.40. Data.--Alberta, Canada, June 6, 1899. Seven eggs. Nest in hole in tree stump, lined with down. Collector, Dr. George.

154. Old-squaw. Harelda hyemalis.

Range.--Northern Hemisphere, breeding in the Arctic regions; south in winter to New Jersey and Illinois.

The Long-tailed Duck, as it is called, is especially noticeable because the breeding plumage of the male differs markedly from that in the winter. In summer their general plumage is blackish brown, with a white patch around the eye, and white belly. In winter they are largely white. The central tail feathers are much lengthened. They breed abundantly in Greenland, Alaska and the Hudson Bay Territory, placing their nests of grasses and weeds on the ground near the water. It is generally concealed in the long grass. The eggs number from six to twelve. Size 2. × 1.50. Data.--N. Iceland, June 10, 1900. Nest on ground, lined with down. Collector, S. H. Wallis.

155. Harlequin Duck. Histrionicus histrionicus.

Range.--Northern Hemisphere in America, breeding from Newfoundland and the Rocky Mountains in Colorado, northward. South in winter to California and New England.

A beautiful and most gorgeous bird, not in colors, but in the oddity of the markings, the colors only including black, white, gray and chestnut. Either sex can be recognized by the small short bill. They breed mostly in single pairs along swiftly running streams, placing their nest, which is woven of weeds and grasses, in the ground near the water. It is also claimed that they sometimes nest in hollow trees. They lay from five to eight eggs, yellowish or greenish buff in color. Size 2.30 × 1.60. Data.--Peel River, Alaska, June 13, 1898. Seven eggs in a hollow in river bank, lined with down. Collector, C. E. Whittaker.

156. Labrador Duck. Camptorhynchus labradorius.

This bird, whose range was from Labrador to New Jersey in the winter, has probably been extinct since 1875, when the last authentic capture was made. It is a strange fact that a bird of this character should have been completely exterminated, even though they were often sold in the markets. Only forty-one specimens are known to be preserved at present and nothing is known in regard to their nesting habits or eggs.

157. Steller's Duck. Polysticta stelleri.

Range.--Arctic regions in America, chiefly on the Aleutian Islands and northwest coast of Alaska.

A very beautiful species eighteen inches long; head white, washed with greenish on the forehead and nape; chin, throat, neck, back, tail and crissum, black; underparts chestnut; wing coverts white, the long scapulars black and white. It breeds on the rocky coasts and islands of Bering Sea. The six to nine eggs are pale olive green in color. Size 2.25 × 1.60. Data.--Admiralty Bay, Alaska, June 22, 1898. Nest on a hummock of the tundra, near a small pool, lined with grass and down. Collector, E. A. McIlhenny.

158. Spectacled Eider. Arctonetta fischeri.

Range.--Coast of Alaska from the Aleutians to Point Barrow.

Like the rest of the true Eiders, this species is black beneath and mostly white above. The head is largely washed with sea green, leaving a large patch of white, narrowly bordered by black around each eye, thus resembling a pair of spectacles. The nests are made of grass and seaweed and lined with down; they are placed on the ground in clumps of grass or beneath overhanging stones. The five to nine eggs are an olive drab or greenish color. Size 2.70 × 1.85. Data.--Point Barrow, Alaska, June 15, 1898. Six eggs. Nest of moss and down in a hollow in dry tundra. Collector, E. A. McIlhenny.

159. Northern Eider. Somateria mollissima borealis.

Range.--North Atlantic coast, breeding from Labrador to Greenland and wintering south to New England.

A large Duck similar to the next species, but with the base of the bill differing, as noted in the description of the following species, and with a more northerly distribution. The nesting habits are the same as those of the other Eiders. Six to ten eggs generally of a greenish drab color. Size 3. × 2.

160. Eider. Somateria dresseri.

Range.--Atlantic coast, breeding from Maine to Labrador and wintering south to Delaware.

This species differs from the preceding only in the fleshy part of the base of the bill, which extends back on each side of the forehead, it being broad and rounded in this species and narrow and pointed in the Northern or Greenland Eider. This species, but more especially the Northern Eider, are the ones chiefly used for the eider-down of commerce. The preceding species is often semi-domesticated in Greenland, the people protecting them and encouraging them to nest in the neighborhood. They make their nests of seaweed and grass and warmly line it with down from their breast; this down is continually added to the nest during incubation until there is a considerable amount in each nest, averaging about an ounce in weight. The birds are among the strongest of the sea ducks and get their food in very deep water. Their flesh is not good eating. Their eggs number from five to ten and are greenish drab. Size 3. × 2.

161. Pacific Eider. Somateria v-nigra.

Range.--North Pacific from the Aleutian Islands northward, and east to Great Slave Lake.

This bird is, in plumage, like the Northern Eider, except that it has a black V-shaped mark on the throat. They nest sparingly on the Aleutian Islands, but in great numbers farther north on the coast about Point Barrow. Their habits, nests and eggs are precisely the same as those of the eastern forms. Their eggs number from five to ten and are of olive greenish color. Size 3. × 2. Data.--Cape Smythe, Alaska, June 8, 1900. Eight eggs. Nest a hollow in the moss, lined with grass and down.

162. King Eider. Somateria spectabilis.

Range.--Northern Hemisphere, breeding in America from Labrador to Greenland and the Arctic Ocean; south in winter to the New England States and rarely farther on the eastern side, and to the Aleutians on the Pacific; also casually to the Great Lakes in the interior.

A handsome and very different species from any of the foregoing, having the crown ashy blue, and the long scapulars black instead of white. It also has a broad V-shaped mark on the throat. Like all the other Eiders, the female is mottled brown and black, the different species being very difficult to separate. The nests are sunk in the ground and lined with down. Eggs number from six to ten. Size 2.80 × 1.80. Data.--Point Barrow, Alaska, July 5, 1898. Five eggs. Nest a hollow in the moss on tundra lined with moss and down. Collector, E. A. McIlhenny.

163. Scoter. Oidemia americana.

Range.--Northern North America, breeding from Labrador, the Hudson Bay region and the Aleutian Islands northward; winters south to Virginia, the Great Lakes and California.

Scoters or "Coots" as they are generally called are sea ducks whose plumage is almost wholly black; they have fantastically colored and shaped bills. The American Scoter is entirely black without markings; base of bill yellow and orange. This species nest as do the Eiders, often concealing the nest, of grass and feathers, under some overhanging rock. They lay from six to ten eggs of a dingy buff color. Size 2.50 × 1.70. Data.--Mackenzie Bay, June 15, 1899. Ten eggs. Nest a hollow in the sand, lined with down.

Buff.

164. Velvet Scoter. Oidemia fusca.

An Old World species that has accidentally occurred in Greenland.

165. White-winged Scoter. Oidemia deglandi.

Range.--Abundant in North America, breeding from Labrador, North Dakota and British Columbia, northward. Wintering south to the Middle States, southern Illinois and southern California.

The largest of the Scoters, length 22 inches, distinguished by a large white speculum on the wing, also a white comet extending from under the eye backwards. It also has a yellow eye. Like the other Scoters, this species often feeds in very deep water. They are strong, active diving birds, and are also strong on the wing, generally flying close to the surface of the water. Their flesh is not regarded as good eating, although they are often sold for that purpose. They nest on the ground, generally in long grass or under low bushes making a coarse nest of grasses, and sometimes twigs, lined with feathers. They lay from five to eight eggs of a pale buff color. Size 2.75 × 1.85.

166. Surf Scoter. Oidemia perspicillata.

Range.--Northern North America, breeding north of the United States boundary, and wintering south to Virginia and southern California.

The male of this species is entirely black, except for the white patches on the forehead and nape, and the vari-colored bill of black, white, pink and yellow. They nest either along the coast or in the interior, building a nest lined with down, in the marsh grass bordering small ponds. They lay from five to eight buffy cream colored eggs. Size 2.40 × 1.70. The females of all the Scoters are a dingy brownish color, but show the characteristic marking of the species, although the white is generally dull or sometimes mottled. Data.--Mackenzie River, June 25, 1894. Six eggs in a nest of down on an island in the river.

167. Ruddy Duck. Erismatura jamaicensis.

Range.--Whole of North America, breeding chiefly north of the United States border except locally on the Pacific coast. Winters along the Gulf and through Mexico and Central America.

This peculiar species may always be recognized by the brownish or chestnut upper parts, blackish crown, white cheeks and silvery white underparts. The bill is very stout and broad at the end, and the tail feathers are stiff and pointed like those of a Cormorant. They build their nests in low marshy places, either placing them on the ground near the water or in the rushes over it. Their nests are made of rushes and grasses, sometimes lined and sometimes not, with down from the parents breast. The eggs number from six to twelve and are grayish in color. Size 2.40 × 1.75. Data.--Northern Assiniboia, Canada, June 6, 1901. Eight eggs. Nest made of aquatic grasses, lined with down. Built in a tuft of rushes in a marsh. Collector, Walter Raine.

168. Masked Duck. Nomonyx dominicus.

This is a tropical species which is resident in Mexico, Central America and in the West Indies. It occurs in Mexico north to the lower Rio Grande Valley and has in three known instances strayed to northern United States. The general plumage is a rusty chestnut, mottled with blackish, it has a black face and throat, with white wing bars.

169. Snow Goose. Chen hyperboreus hyperboreus.

Range.--North America west of the Mississippi Valley, breeding in northern Alaska and the MacKenzie River district.

This smaller species of the Snow Goose nests on islands in rivers along the arctic coast. The nest is a depression in the ground, lined with grasses and, occasionally down. They lay from four to eight eggs of a buffy or yellowish white color. Size 2.75 × 1.75.

169a. Greater Snow Goose. Chen hyperboreus nivalis.

Range.--Eastern North America, breeding in the Arctic regions and wintering chiefly on the Atlantic coast, south to Cuba.

This bird is like the preceding; except in size; about thirty-six inches, instead of twenty-six inches in length as is the lesser variety. The entire plumage is white except for the black primaries. They construct their nests of grasses on the ground the same as the preceding variety. The eggs number from five to eight and are cream colored. Size 3.40 × 2.40.

169.1. Blue Goose. Chen cærulescens.

Range.--North America, principally in the interior, breeding from Hudson Bay northward and wintering along the Gulf coast.

This species may always be recognized by the entirely white head and neck, the body being grayish or bluish gray. They nest on the ground as do the other geese laying from four to eight eggs of a brownish buff color. Size 2.50 × 1.75. Data,--Cape Bathurst, Arctic coast, June 29, 1899. Four eggs laid in a depression lined with grass, on an island. Collected with the parent birds by the Esquimaux.

170. Ross's Snow Goose. Chen rossi.

Range.--This beautiful species, which is similar in plumage to the large Snow Goose, is but twenty-one inches in length. It breeds in the extreme north, and in winter is found in the western part of the United States as far south as the Gulf of Mexico. Their nesting habits and eggs probably do not differ from others in the family except in the matter of size.

171. White-fronted Goose. Anser albifrons albifrons.

This European species is exactly like the American except that it is said to average a trifle smaller. It is occasionally found in Greenland.

171a. American White-fronted Goose. Anser albifrons gambeli.

Range.--Whole of North America, breeding in the Arctic regions and wintering south to the Gulf coast; not common on the Atlantic coast during migrations.

These birds may be recognized by their mottled plumage, dark head and white forehead. This species is more abundant than any of the preceding and nests in large colonies along the arctic coast and in Alaska. Their nests are made of dried grasses, feathers and down and are placed on the ground in a slight depression. From four to nine eggs are laid; these have a dull buff ground. Size 3.00 × 2.05. Data.--Island in delta of Mackenzie River, June 10, 1899. Four eggs. Nest of grass and feathers on the ground on a small island. Collector, Rev. I. O. Stringer.

[Illustration z110: ]

171.1. Bean Goose. Anser fabalis.

This European species is casually found in Greenland. It is one of the most common of the Old World Species.

172. Canada Goose. Branta canadensis canadensis.

Range.--The whole of North America, breeding from northern United States northward, and wintering in the southern parts of the United States.

This species is the most widely known of American Geese and is the most abundant. Its familiar "honk" has long been regarded as the signal of the coming of spring, and the familiar V-shaped formation in which the flocks migrate is always an object of interest to everyone. With the exception of in North Dakota and Minnesota, they breed chiefly north of the United States. They construct quite a large nest of weeds and grass, and warmly line it with down and feathers. They lay from four to nine eggs of a buff or drab color. Size about 3.50 × 2.50. Data.--Ellingsars Lake, North Dakota, May 18, 1896. Five eggs. Nest on an island in the lake, constructed of weeds and trash, and lined with a few feathers. Collector, Edwin S. Bryant.

172a. Hutchins Goose. Branta canadensis hutchinsi.

This sub-species is like the preceding except that it is smaller, thirty inches in length. It is a western variety, breeding in Alaska and along the Arctic coast and wintering to southern California. Its breeding habits, nests and eggs are the same as the common goose except that the eggs are smaller. Size 3.00 × 2.05.

172b. White-cheeked Goose. Branta canadensis occidentalis.

This bird is about the same size as the Canada Goose and the plumage is very similar except that the black sometimes extends on the throat, thereby isolating the white cheek patches, and there is a white collar below the back of the neck. It is a western species, breeding in Alaska and wintering along the Pacific coast of the United States. Its nesting habits and eggs are same as those of the Canada Goose except that the latter are a trifle smaller.

172c. Cackling Goose. Branta canadensis minima.

This bird is really a miniature of the Canada Goose, being but twenty-four inches in length. It breeds in Alaska and along the Arctic coast and migrates into the western parts of the United States. They are abundant birds in their breeding range, where they place their nests upon the shores of ponds, or on islands in inland rivers or lakes. The nests are made of weeds and grasses, lined with down. The eggs which are buff colored, number from four to nine and are laid during June and July. Size 2.30 × 1.95.

CANADA GEESE.

173. Brant. Branta bernicla glaucogastra.

Range.--Eastern North America, breeding in the Arctic regions and wintering in the United States east of the Mississippi.

The Brant resembles a small Canada Goose, except that the black of the neck extends on the breast, and only the throat is white. They are one of the favorite game birds and thousands are shot every fall and spring. Their nests and eggs are the same as the next species.

174. Black Brant. Branta nigricans.

Range.--Western North America, breeding in Alaska and wintering on the Pacific coast of the United States. Rare east of the Mississippi.

This species is like the last except that the black extends on the under parts. This species nests very abundantly in northern Alaska, laying their eggs in a depression in the ground, lined with down. Favorite locations are the many small islets in ponds and small lakes. They lay from four to eight grayish colored eggs. Size 2.80 × 1.75. Data.--Cape Bathurst, North West Territory, Junes 22, 1901. Seven eggs in a small hollow in the ground, lined with down. Collector, Capt. H. H. Bodfish.

175. Barnacle Goose. Branta leucopsis.

This Old World species occurs frequently in Greenland and very rarely is found on the mainland of this continent.

176. Emperor Goose. Philacte canagica.

Range.--Alaska, south in winter casually to California.

This handsome species is twenty-six inches in length; it may be known from the mottled or "scaly" appearance of the body, and the white head with a black chin and throat. While not uncommon in restricted localities, this may be considered as one of the most rare of North American Geese. Their nests are built upon the ground and do not differ from those of other geese. They lay from three to seven eggs of a dull buff color. Size 3.10 × 2.15. Data.--Stuart Island, Alaska, June 16, 1900. Six eggs laid in a slight hollow in the ground, lined with a few feathers and some down. Collector, Capt. H. H. Bodfish.

Egg of Canada Goose--Buffy drab.

177. Black-bellied Tree-duck. Dendrocygna autumnalis.

Range.--Tropical America, north in the Rio Grande Valley to southern Texas.

These peculiar long-legged Ducks are very abundant in southern Texas during the summer months. They build their nests in hollow trees, often quite a distance from the water. They lay their eggs upon the bottom of the cavity with only a scant lining, if any, of feathers and down. They are very prolific breeders, raising two broods in a season, each set of eggs containing from ten to twenty. These eggs are creamy or pure white, size 2.05 × 1.50. The first set is laid during the latter part of April or early in May, and fresh eggs may be found as late as July. They are especially abundant about Brownsville and Corpus Christi, Texas. Data.--Hidalgo, Mexico, May 29, 1900. Ten eggs in a hole in an old elm tree on side of lake in big woods near town. Eight feet from the ground. Collector, F. B. Armstrong.

178. Fulvous Tree-duck. Dendrocygna bicolor.

Range.--This species is tropical like the last, but the summer range is extended to cover, casually the whole southwestern border of the United States.

This bird is long-legged like the last, but the plumage is entirely different, being of a general rusty color, including the entire under parts. The nesting habits and eggs are the same as those of the Black-bellied Duck, the white eggs being laid at the bottom of a cavity in a tree. They number from eight to (in one instance) thirty-two eggs in one nest. This species is nearly as abundant as the preceding in southern Texas.

179. Whooper Swan. Olor cygnus.

This European variety frequently is found in Greenland and formerly, regularly bred there. It nests in secluded swampy places in northern Europe.

180. Whistling Swan. Olor columbianus..

Range.--North America, breeding in the Arctic Circle, and wintering south to the Gulf of Mexico.

These birds, which are nearly five feet in length, are snow white with the exception of the black bill and feet. The Whistling Swan is distinguished from the next species by the presence of a small yellow spot on either side of the bill near its base. Their nests are made of a large mass of rubbish, weeds, grass, moss, feathers and occasionally a few sticks. It is generally placed in a somewhat marshy place in the neighborhood of some isolated pond. The eggs are of a greenish or brownish buff color, and number from three to six. Size 4.00 × 2.75. Data.--Mackenzie River. Nest a mass of weeds, sods and grass, lined with feathers; on an island near the mouth of the river. Collector, I. O. Stringer.

181. Trumpeter Swan. Olor buccinator.

Range.--Interior of North America from the Gulf of Mexico northward, breeding from northern United States northward.

This is a magnificent bird, about five and one-half feet in length. Its plumage is exactly like that of the preceding except that the bill is entirely black, and the nostril is located nearer the eye. Their nesting habits and eggs are the same as those of the Whistling Swan. While a few pairs may breed within the United States by far the greater number are found in the extreme north, from Hudson Bay to Alaska. The eggs may average a trifle larger than those of the preceding species.
