What bird is that?

The Mourning Warbler is one of the rarer Warblers which, by good fortune, we may occasionally see toward the end of the spring migration. It is usually found in the lower growth, being a brush and tangle haunter of woods and clearings. Its song, which is described as clear and ringing, is uttered frequently, often from a dead limb. The nest is built in briars or bushes within a foot or two of the ground. The eggs, laid in the first half of June, are white with a few brownish spots at the larger end.

A fidgety, inquisitive inhabitant of bushy undergrowth along roadsides and wood borders, whose impatient off-repeated call-note, chack, chack, and energetic song of wichity, wichity, wichity, soon become familiar to the bird-student. It nests on or near the ground and the white, lightly spotted eggs are laid in the latter half of May.

The Florida Yellow-throat (G. t. ignota), a more deeply colored race, is found from North Carolina to southern Florida. In the last-named State it usually inhabits scrub palmetto growths.

If the Chat lived in England what a wealth of lore, legend, and literature would owe its origin to his strange ways and stranger notes! Here he is known to few but the initiated, who find an endless interest in his odd song-medley and peculiar antics. Go yourself to the brush-grown, thickety wood borders and clearings he loves and let him be his own interpreter. You may even find his nest low down in some crotch with its white, evenly speckled eggs, and hear his angry chŭt as he resents your presence.

Color, song, habit and temperament combine to make the Hooded Warbler one of the most attractive members of its family. As one sees it flitting from bush to bush in woodland undergrowth, displaying its white outer tail-feathers as it flies, pausing now and again to utter its simple, sweet whistled song, one is impressed not only by its beauty but by its gentleness. It nests in a bush within a foot or two of the ground, laying 3-5 white eggs, wreathed with shades of brown spots, early in May, in the South, in June, in the North.

Wilson's Warbler, a flycatching Warbler of the lower growth, favors bushes near water, but is also found in dryer places. Thayer in "Warblers of North America" says that its "song has much of the ringing clarity of the Canada's and Hooded's songs." It nests on the ground, laying 4 eggs, usually with a wreath of spots at the larger end, early in June.

The Canadian Warbler haunts the lower growth of deciduous forests. It is "a sprightly, wide-awake, fly-snapping Warbler, vivid in movement and in song" (Thayer). "The song is liquid, uncertain, varied, bright and sweet" (Farwell). It nests on the ground early in June, laying 4-5 eggs much like those of Wilson's Warbler.

His bright colors, graceful, aerial pirouetting, abundance, and frequently uttered song make the Redstart the most conspicuous as well as one of the most attractive of our woodland Warblers. So exquisite a creature should be as widely known as are violets or daisies. The Redstart builds its well-made nest in a crotch, usually about fifteen feet above the ground. The 4-5 grayish white eggs, spotted and blotched chiefly at the larger end, are laid in mid-May.

WAGTAILS AND PIPITS. FAMILY MOTACILLIDÆ

At first glance a Pipit might be mistaken for a Sparrow—let us say, a Vesper Sparrow; but note that it walks, instead of hops, that it constantly wags or 'tips' its tail, that it has a slender, not stout bill. Meadows, pastures, plowed fields, golf-courses, are frequented by Pipits, usually in flocks of a dozen or more. When flushed, with a faint dee-dee, they bound lightly into the air but usually soon return to earth.

Sprague's Pipit (Anthus spraguei), a slightly smaller species, nests in Montana, Dakota, and northward, and is sometimes found in small numbers on the coast of South Carolina and Georgia in winter.

THRASHERS, MOCKINGBIRDS, ETC. FAMILY MIMIDÆ

No southern garden is complete without a Mockingbird to guard its treasures with his harsh alarm-note and extol its beauties in his brilliant, varied song. He is to the South what the Robin is to the North—and more, for he is present throughout the year while the Robin is with us only during the nesting season.

The Mocker builds in bushes, orange-trees or other dense vegetation, from late March, in southern Florida, to early May in Virginia. The 4-6 eggs are blue heavily marked with brown.

If the Catbird's name were based on his song instead of on his call-note, he might have won the popularity he deserves, but which seems forever denied him. Taking kindly to civilization he makes his home near ours, asking only the shelter of our shrubbery and a share of our small fruits in return for three months of music such as but few birds can produce.

The Catbird nests in bushes and thickets laying 3-5 greenish blue eggs in May.

In the wealth of new experiences and awakened associations which crowd the bird-lover's days in April and May, none stands out more clearly in my memory than the first Thrasher's song.

The rich, distinctly enunciated notes ring loud and clear above all other songs as the bird from some tree-top gives his musical message to the world. The performance concluded he returns to the undergrowth whence one may hear his explosive, whistled wheèu or sharp kissing note. The nest is built in bushy growths or on the ground in May. The 3-6 eggs are grayish white finely speckled with reddish brown.

WRENS. FAMILY TROGLODYTIDÆ

The Carolina Wren is a bird of the woods, whose loud, musical whistles are among the most conspicuous of southern bird notes. They suggest those of both the Cardinal and Tufted Titmouse, but are more varied in character. A common scolding call is recognizably wren-like, while another suggests a tree-toad's krrring. The nest is built in holes, in April. The 4-6 eggs are white with numerous reddish brown and lavender markings.

A house Wren of the States west of the Alleghanies with a tail that seems to be at the mercy of passing breezes, and a song resembling the Song Sparrow's, but louder. Its nesting habits resemble those of the House Wren. The 4-6 eggs, laid in April, are white speckled with reddish brown and lavender.

The familiar inhabitant of our bird-houses whose numbers seem limited only by the nesting-sites we offer him. His little fountain of melody bubbles forth irrepressibly to cheer his mate or challenge a rival. With the exhaustless energy of their kind they fill their nest-box with twigs, grasses and feathers, wherein are laid 6-8 minutely and evenly speckled pinkish eggs.

The Winter Wren comes to us from the North when the House Wren leaves for the South and remains with us until the House Wren returns in the spring. But one by no means takes the place of the other. The Winter Wren is a wood Wren that lives in fallen tree-tops, old brush-piles or similar retreats, and his nervous chimp, chimp, as with cocked-up tail he hops into view for a second, is like the call of the Song Sparrow rather than the scolding note of most Wrens; nor does his rippling, trickling song resemble the House Wren's sudden outburst.

The nest is built in the roots of a tree or similar location. The 5-7 eggs, laid in early June, are white, finely, but rather sparingly speckled with brownish.

Although we have only six species of Wrens in the eastern United States, they are so unlike in their choice of haunts that few localities which will afford them the hiding places they all love are without one or more of them. The House and Bewick's Wrens make their homes near ours; the Carolina and Winter Wrens prefer the woods; the Long-billed Marsh Wren's haunts have given him his name, and if we should call the present species Meadow Wren, its home would be similarly indicated, for it lives in wet, grassy places rather than among the cat-tails.

Ernest Seton describes its note as resembling the sound produced by striking two pebbles together, while its song is a series of chaps, running into chap-r-r-rrr. The globular nest is built on the ground, and the 6-8 eggs, laid in May, are usually pure white.

As well look for pond lilies on a rocky hillside as a Marsh Wren outside a marsh. Give him cat-tails for cover and to support his bulky nest and he is at home. His scolding notes betray his ancestry and his reeling, rippling song, delivered both from a perch and on fluttering wings above the reeds, suggests in form, at least, that of the House Wren. The 5-9 eggs, laid in early June are uniform chocolate or thickly marked with brown.

CREEPERS. FAMILY CERTHIIDÆ

To see the Brown Creeper is to knew him but so inconspicuous is he that unless you chance to observe him drop from one to tree near the foot of another, you may overlook the little figure creeping spirally upward. Nor are his thin, weak, squeaky call-notes more likely to attract attention than he is himself. A true bird of the bark, he not only hunts upon it but builds his nest behind it, laying 5-8 white, brown-spotted eggs in May.

NUTHATCHES. FAMILY SITTIDÆ

During the summer we will see comparatively little of this bird who, with equal ease, climbs either down or up a tree trunk, but in the winter he will be a constant patron of the nuts and suet on our lunch counters. Habit, markings, his unmistakable yank-yank, all distinguish him from our other birds, except his Canadian cousin to which, after all, he bears only a family resemblance.

In April, 5-7 white, brown speckled eggs are laid in a hole in a tree, lined with feathers, etc.

Late in August when I hear a note such as one might imagine a baby Nuthatch would utter, I know that the Red-breasted Nuthatch has arrived from the north perhaps to spend the winter, or, may be, to go farther south. He never seems quite as familiar as his larger, louder-voiced, white-breasted cousin, and if one wants to make his acquaintance it is well to follow the sound of his penny-trumpet-like notes until their author is discovered.

The Brown-headed Nuthatch is a bird of southern pine forests; one may travel for miles without seeing a single individual and then discover a company of a score or more. They pass most of their time among the upper branches uttering a pit-pit as they hunt for food, or all suddenly joining in a metallic tnee-tnee-tnee, when they are apt to take flight to the adjoining trees. The nest is in a hole in a tree or stump, generally near the ground; 5-6 white, heavily marked eggs being laid in March.

TITMICE. FAMILY PARIDÆ

The loud peto, peto, peto of the Tufted Tit can be confused only with certain notes of the Carolina Wren, but while skilfull stalking is required to see the Wren, one may walk up and inspect the Tit with little or no caution. When he sees us he may change his call to a hoarse dee-dee-dee which at once betrays his relationship to the Chickadee. The nest is made in a hole, and the 5-8 white, brown-marked eggs are laid in April.

While the Chickadee is with us throughout the year, it is during the winter that he takes first place in our affections. Active, cheerful, friendly, he is an ever welcome visitor to our lunch-counters, and often shows complete and winning confidence in us by perching on our hands. His clearly enunciated chick-a-dee, with its variations, we accept as his characteristic language, but the sentiment expressed in his two- or three-noted whistle seems to belong to the Pewee rather than the sprightly Black-cap. It is, in fact, often falsely attributed to that bird, even when our books tell us that the Pewee is wintering in the tropics!

The Chickadee nests in holes, usually within ten feet of the ground, laying 5-9 white, brown-speckled eggs in the first half of May.

Whether because of a different temperament or because milder winters make him less dependent on man's bounty, the Carolina Chickadee does not show that unquestioning confidence in our good faith which makes the Black-cap so dear to us.

The chick-a-dee note is less clearly and more hurriedly given by the Carolina, and the pe-wee whistle is not so loud and usually consists of four notes instead of two. The nesting habits and eggs of the two species are alike, but the southern bird begins to lay in March.

Until recent years the Brown-capped Chickadee was rarely seen far south of its breeding range, but during several winters it has invaded New England in considerable numbers and has been found in the lower Hudson Valley, Long Island, Staten Island and northern New Jersey. At close range an experienced observer may know it by its dark brown head, while Brewster states that its "nasal, drawling, tchick, chee-day-day" at once distinguishes it from the Black-cap. All three races have been reported in these winter migrations and only expert examination of specimens can determine whether the little wanderer is from Labrador, New Brunswick, or the country west of Hudson Bay.

OLD-WORLD WARBLERS, KINGLETS AND GNATCATCHERS. FAMILY SYLVIIDÆ

It is surprising, in the depth of winter, when in great coat and muffler we keep warm only by vigorous exercise, to see these dainty, feathered mites, unconcerned by the temperature, flitting here and there in their search for insects' eggs and larvæ. They have small fear of man and we may readily approach near enough to hear their thin ti-ti or see their golden-crown. In proportion to its size, this diminutive species lays a larger number of eggs than any other of our birds, as many as 9 or 10 white, brown-marked eggs being laid in their pensile, mossy nest in the latter part of May.

A tiny, olive-green bird, with a large white eye-ring, fluttering actively among the yellowing leaves, uttering from time to time a wren-like cack as he twitches his wings and showing little or no fear of man can be only the Ruby-crown, southward bound. He returns before the trees are clad, as the author of a song as marvelous in volume as it is musical in tone; a whistled song of rare sweetness.

In color, form, proportions and voice, the Gnatcatcher may properly be called 'dainty.' His slightly explosive call-note tin-ng, is louder than his exquisitely finished, varied, miniature song. The nest is almost as fine in workmanship as a Hummer's. The 4-5 white, thickly speckled eggs, are laid in April and early May.

THRUSHES, BLUEBIRDS, ETC. FAMILY TURDIDÆ

Most familiar of our Thrushes. From late April to early August his bell-like notes are heard, not only in the forest, but in wood-bordered village streets and from the shade trees of our lawns. His sharp, pebbly, pit-pit, is prominent in the chorus of protesting notes which greet the Screech Owl should he leave his retreat before diurnal birds have gone to bed.

The nest is usually built in small trees about 8 feet from the ground. The 3-5 greenish blue eggs are laid in May. There is a second brood in June.

Low, wet woods with considerable undergrowth, where skunk cabbage and hellebore flourish are the home of the Veery. Here he winds his mysterious double-toned spiral song, and here, on the ground, hidden beneath the rank vegetation, he builds his nest. The eggs, laid late in May, resemble those of the Wood Thrush. The Veery's common call is a clearly whistled wheé-you, quite unlike the quirt or pit-pit of the Wood Thrush. Except in mountainous regions and some local 'stations,' the Wood Thrush and Veery are the only Thrushes which nest in the eastern United States south of Massachusetts.

The Gray-cheeked and Bicknell's Thrushes are merely the larger northern and smaller southern forms, respectively, of the same species. They are known in the United States chiefly as migrants and can be distinguished with certainty in life only by an expert under favorable conditions. The larger form is the commoner. The species may be known from the Veery and Wood Thrush by its olive, instead of cinnamon-brown back, and from the Olive-backed Thrush by its whitish eye-ring and paler breast.

Brewster describes the song of the southern form (Bicknell's Thrush) as exceedingly like that of the Veery but more interrupted, while the ordinary call-note is practically identical with the pheu of the Veery. The nest is placed in low trees or bushes. The eggs are greenish blue spotted with brown.

We know this Thrush chiefly as a migrant when, in the latter part of May, and again in September and October, it passes us en route to and from its northern home. At these seasons we may even hear its whistled puit from the sky as it journeys through the night. "Its song," Dwight says, "lacks the leisurely sweetness of the Hermit Thrush's outpourings, nor is there pause, but in lower key and with greater energy it bubbles on rapidly to a close rather than fading out with the soft melody of its renowned rival."

The Olive-back nests in bushes or low trees, and lays 3-4 greenish blue brown-spotted eggs in June.

The Hermit is the only one of the Thrushes to winter in the eastern United States and it is, therefore, the first one to reach us in the spring. It comes early in April and takes about a month to complete its migration. It rarely sings at this season and then only an echo of the heavenly music which has won for it first place among American songsters.

We may know the Hermit Thrush by the season in which he visits us, by his reddish brown tail, which he slowly raises and lowers after alighting, and by the low chuck note with which he usually accomplishes this movement.

The Hermit nests on the ground, laying, in the latter part of May, 3-4 greenish-blue eggs, slightly lighter in tint than those of the Wood Thrush.
