Family SYLVIIDÆ.

Bill slender, short or moderately long; upper mandible with a small notch; culmen slightly curved near the tip; nostrils exposed; rictal bristles usually inconspicuous; wing rounded and curved to the body, tertials much shorter than secondaries; tarsus slender, longer than bill from gape; tail rounded, wedge-shaped, or graduate. Nearly all the members of this family are plainly colored and the sexes closely resemble each other. The young birds are unspotted; they either resemble the adults, or else they are more highly colored. Some of the genera of flycatchers are very similar to certain genera which are here placed in the Sylviidæ.

Characteristic species of the Turdidæ, Muscicapidæ, and Sylviidæ are easily recognized and distinguished, but the three families intergrade through intermediate genera so that even the highest authorities on classification are by no means agreed as to the respective limits of these three families.

Adult (sexes similar).—Above olivaceous russet-brown, each feather with a wide seal-brown shaft-streak; primaries and secondaries seal-brown edged with russet-brown, second primary edged with whitish; secondary-coverts similar to back; tail nearly uniform brown; sides of head and ear-coverts brown; a yellowish buff line above, and another below, eye; cheek and jaw buff, traversed by a narrow blackish brown line; under parts whitish, washed with buff on fore breast, sides, flanks, and crissum; feathers of these parts more or less marked with blackish brown shaft-lines. Bill dusky above, flesh-color below; legs and nails pale yellowish flesh-color. Length, 120 to 125. A male from Calayan measures: Wing, 57; tail, 45; culmen from base, 12; bill from nostril, 7; tarsus, 17. A female, wing, 53; tail, 43; culmen from base, 11; bill from nostril, 7; tarsus, 19.

“The streaks on the lower surface become reduced in aged birds. The bird least marked in my series has a few streaks only on the middle of the breast and on the flanks, with one or two faint marks on the under tail-coverts. In this state it is very like the Indian L. straminea. The majority of the birds are densely streaked from the chin to the tail-coverts, except on the abdomen; and all these are characterized by a richer tone of coloring beneath. The tail-coverts vary in the most extraordinary manner. In many of the birds they are entirely unmarked; in others densely streaked, and this apparently quite independently of the amount of streaking on the other parts of the lower plumage.” (Oates.)

“Clearly the nearest allies to this species are L. luteiventris and L. mandellii. In these three species the wing-formula is as follows:

L. luteiventris. Fourth quill slightly longer than, rarely subequal to, the fifth; third intermediate between fifth and sixth.

L. mandellii, L. seebohmi. Fifth somewhat longer than the fourth and sixth, which are subequal, and distinctly longer than the third.

“The present species differs from both its allies in having the general color of the upper parts browner, the white on the chin and throat more extensive and shading into grayish on the sides of the neck; while the sides and flanks are more grayish brown in tint and but slightly washed with buff; the lower mandible appears to have been yellowish white, as in L. luteiventris. Length, 147; wing, 51; tail, 63.5; tarsus, 20; middle toe with claw, 19.” (Grant.)

“Steere has attempted to separate the Panay tailorbird from that of Guimaras and Negros, but after a most careful examination of a large series of specimens from Panay, Negros, and Masbate we are compelled to say that there is not the slightest difference between the birds from the three islands. Their size is the same. The wash of olive-green on the back, on which Doctor Steere relied to separate the Panay birds, is a variable character present in some birds, absent in others shot at the same season. It occurs in birds from Negros and Masbate as well as those from Panay. The presumptive evidence against finding one species of Orthotomus in Panay and another in Guimaras is of course very strong. Guimaras is to all intents and purposes a part of Panay and there are no other known differences between the birds of the two islands. Masbate is a new locality for the species.” (Bourns and Worcester.)

“The chestnut-headed tailorbird frequents low bushes in open country, also the mangrove swamps; less common in the woods. A noisy bird, its note being very similar to that of O. frontalis.” (Bourns and Worcester MS.)

Bohol (McGregor); Leyte (Whitehead); Samar (Steere Exp., Bourns & Worcester, Whitehead).

Adult male.—Entire head, neck, chin, throat, and middle of fore breast black; back and rump dull olive-green brighter around the neck; rump and tail-coverts dull russet-brown; wing-feathers blackish, edged with olive-green, the bend of wing and tips of greater median coverts yellow; rectrices brown, edged with russet; breast, sides of breast, and of neck, and abdomen lemon-yellow becoming olivaceous on sides, flanks, and crissum; thighs dull chestnut. The black of fore breast is sharply defined against the yellow, and does not extend over the sides of the chest as it does in O. nigriceps, but is confined to the central parts of the chest, its posterior outline being rounded. All the specimens known have more or less white on the chin and malar region, but this is variable in extent and is probably a sign of immaturity as it is in O. nigriceps. A male from Bohol measures: Length, 127; wing, 44; tail, 39; culmen from base, 15; bill from nostril, 11; tarsus, 21.

The female is unknown.

“Iris light brown; bill brownish black, mandible pinkish brown; legs yellowish flesh-color. This bird has a sweet and powerful song and in this respect it differs from the other species. It is very shy and difficult to obtain.” (Whitehead.)

“The yellow-breasted tailorbird is extremely rare. A single specimen was secured by the Steere Expedition, and we were able to secure but one more. Both birds were shot in deep forest close to the bank of a stream. Our specimen, a male, measures: Length, 114; wing, 42.6; tail, 40; culmen, 19; tarsus, 21; middle toe with claw, 18. Iris chocolate-brown; legs, feet, and nails very light brown; bill black. Breeding in August.” (Bourns and Worcester MS.)

Genus CISTICOLA Kaup, 1829.

Bill small, slender, and sharply pointed; culmen gently curved in its terminal half; bill from nostril equal to hind-toe without claw; wing somewhat rounded and flat; difference between the length of primaries and of secondaries less than first primary; first primary slender, much less than one-half the second, the latter nearly as long as third; fourth and fifth equal and longest; rectrices long, much graduated, their tips rounded; the tail is similar to that of Orthotomus, but the feathers are much wider; tarsus and feet well developed, the outstretched toes reaching to or beyond tip of tail. Birds of this genus present puzzling seasonal changes of plumage. The tail is longer in the winter than in the breeding season, and the female is somewhat smaller than the male. The seasonal variation in color is great and has led ornithologists to name several species which do not exist. It is not certain that the smaller species found in the Philippines is really C. exilis, and it may be either C. erythrocephala Jerdon or C. semirufa Cabanis.74

On the authority of Colonel Legge, Sharpe says that in the male the inside of the mouth is black, while in the female it is fleshy.

“Common in the deep grass of the open fields. The habits of the various species of this genus found in the Philippines are practically the same. They live in the grass, and when flushed fly in a curious, jerky way for a short distance, and then drop back into the grass where they instantly disappear. They sometimes perch on tall grass stems or low bushes, and make a series of noises more like the notes of some great grasshopper than those of a bird. We several times found them perched in trees and singing. Four females from Mindanao measure: Length, 105; wing, 46; tail, 38; culmen, 12; tarsus, 19; middle toe with claw, 17. Legs, feet, and nails pale reddish brown; upper mandible nearly black, lower pale at tip, black at base.” (Bourns and Worcester MS.)

“The striated marsh warbler is found about the open fields. It runs rapidly on the ground and skulks in bamboo thickets and patches of tall grass and weeds. It soars and attempts to sing while on the wing; also perches at the very top of bamboo clumps, and ‘sings’ vigorously.” (Bourns and Worcester MS.)

Coloration.—Upper plumage olive-green, lighter on the rump; wings brown, the outer webs edged with olive-green; wing-coverts brown on the inner and olive-green on the outer webs; the median and greater coverts with yellowish white tips forming two bars; tail brown, the outer webs edged with olive-green; a broad and well-defined eye-streak, reaching to the nape, yellowish white; lores brown; ear-coverts olive mingled with yellowish; under plumage white, suffused with yellow; under wing-coverts and axillars pale yellow.

“As the summer goes on the wing-bars get worn away and the upper one is sometimes absent. The lower plumage gets whiter and the upper plumage duller. After the autumn molt the wing-bars are very conspicuous and the under parts become suffused with deeper yellow.

“Upper mandible dark brown, the edges and tip yellow; gape and basal half of the lower mandible orange-yellow, terminal half dusky; mouth bright orange-yellow; iris dark brown; legs flesh-color tinged with yellow; claws yellowish horn-color. Length, 122; tail, 51; wing, 68.5; tarsus, 20; bill from gape, 17; the second primary is intermediate in length between the fifth and sixth, and is sometimes equal to the sixth; the first primary is very small, measuring from 7.6 to 11.4 in length.” (Oates.)

The arctic willow warbler is the commonest species of the genus and is found in the Philippines during the winter months. Most of the specimens taken at this time have the under parts but faintly suffused with yellow and in this plumage the wing-bar is indicated by light spots on the outer webs of some of the greater coverts. This plainly colored species is usually seen flitting among the branches of forest trees and at such heights that it can not be distinguished from other species of similar habits.

“The changes of plumage in this species are similar to those of the preceding species, but at all seasons of the year the general color of the under parts is much paler in color in P. borealis (Blasius). The smaller size and smaller first primary of the latter species serve, however, to distinguish even birds of the year from the present species, though they approach each other very closely.” (Swinhoe.)

The yellow willow warbler is undoubtedly much rarer in the Philippines than the next preceding species, but upon a careful examination of available material I find it necessary to refer to this species a number of specimens which were previously recorded as A. borealis. These changes will be found in the list of localities under each species.

570. ACANTHOPNEUSTE LUGUBRIS (Blyth).
MOURNING WILLOW WARBLER.
  • Phyllopneuste lugubris Blyth, Ann. & Mag. Nat. Hist. (1843), 12, 98.
  • Phylloscopus lugubris Seebohm, Cat. Birds Brit. Mus. (1881), 5, 48.
  • Acanthopneuste lugubris Sharpe, Hand-List (1903), 4, 217; McGregor and Worcester, Hand-List (1906), 90.

Basilan (Steere Exp.); Mindanao (Steere); Samar (Steere Exp.). Western China to Chuan-che, eastern Himalayas; in winter to eastern Bengal and Burmese provinces.

Coloration.—Very similar to A. magnirostris, but rather darker and smaller, and differing also in the proportions of the primaries. Upper mandible dark brown, lower one yellowish, somewhat dusky on the terminal half; iris brown; mouth yellow; legs brown; claws horn-color. Length, 127; tail, 53; wing, 66; tarsus, 19; bill from gape, 15.7; the second primary is intermediate in length between the ninth and tenth, and sometimes equals the tenth; the first primary is very long, being sometimes 20.3 mm. in length.” (Oates.)

I have not seen a full description of this species; it is usually compared with A. magnirostris, but its very long first primary would seem to be a character sufficient to prevent its being mistaken for either of the other species found in the Philippine Islands.

Genus HORORNIS Hodgson, 1845.

Bill short and stout with a small notch near the tip; rictal bristles few and well developed, a few short bristles in front of them; some feathers of forehead and chin with long bristle-like shafts; wing moderate to short, somewhat pointed, or else rounded, either shorter or longer than tail; first primary well developed but much (one-third to one-half) shorter than second, the latter considerably shorter than third; tail strongly rounded; tarsus and feet strong, hind toe and claw heavy; bill from nostril, less than one-half the tarsus, and equal to the hind toe without claw. Colors earthy brown, buff, and white; spots and bars entirely wanting.

Species.
  • a1. Larger, wing more than 70 mm. canturians (p. 587)
  • a2. Smaller, wing less than 65 mm.
    • b1. Fourth and fifth primaries nearly equal and longest; wing longer and about equal to tail. minutus (p. 587)
    • b2. Fifth and sixth primaries nearly equal and longest; wing shorter and much shorter than tail seebohmi (p. 588)

Apo (Celestino); Calayan (McGregor); Luzon (Whitehead, McGregor). Southern Ussuri Land to Lake Chanka, Formosa; in winter to Cachar and southern China.

Adult.—Above nearly uniform wood-brown; lighter on rump and tail-coverts; a dusky spot before and behind eye; eyelids white; a whitish line from bill over eye to nape; cheeks and ear-coverts buffy brown; under parts white, washed with buff on sides, flanks, crissum, and across fore breast; thighs slate-gray; wings brown, the feathers edged with russet; tail brown; axillars, wing-lining, edge of wing, and inner edges of quills white. Iris brown; bill dark brown above and light below; legs light horn. A male from Calayan measures: Length, 170; wing, 77; tail, 75; culmen from base, 16; bill from nostril, 9; tarsus, 27.

572. HORORNIS MINUTUS (Swinhoe).
LITTLE BUSH WARBLER.
  • Arundinax minutus Swinhoe, Ibis (1860), 52.
  • Cettia minuta Seebohm, Cat. Birds Brit. Mus. (1881), 5, 141.
  • Horornis minuta Sharpe, Hand-List (1903), 4, 236; McGregor, Bull. Phil. Mus. (1904), 4, 30; McGregor and Worcester, Hand-List (1906), 91.

Calayan (McGregor). Hainan, Askold Island, southern China.

Adult.—This species differs from H. canturians in being much smaller, and the tail-feathers appear to be less pointed. Length, about 145. A male from Calayan measures: Wing, 62; tail, 61; culmen from base, 14; bill from nostril, 9; tarsus, 22. A female, wing, 62; tail, 60; culmen from base, 13; bill from nostril, 8; tarsus, 22. Exposed portion of first primary little more than one-half of second; fourth and fifth equal and longest.

In the Philippine Islands the little bush warbler is known only as a winter visitant to Calayan Island.

573. HORORNIS SEEBOHMI (Grant).
PHILIPPINE BUSH WARBLER.
  • Cettia seebohmi Grant, Ibis (1894), 507; Whitehead, Ibis (1899), 211 (habits, note).
  • Horornis seebohmi Sharpe, Hand-List (1903), 4, 236; McGregor and Worcester, Hand-List (1906), 90.

Luzon (Whitehead, McGregor).

Adult.—Above dusky wood-brown, slightly olivaceous on the back and more russet-brown on the rump, tail-coverts, and margins of the rectrices; wings brown, the quills edged with russet; the first three primaries, however, fringed with much lighter brown; wing-coverts olivaceous; eyelids and eye-stripe whitish or pale buff; a dusky spot before and behind eye; under parts whitish; sides of neck and breast washed with olivaceous; flanks and crissum yellowish buff; thighs brown. Iris light brown; upper mandible dusky, lower mandible, legs, and nails flesh-color. Length, about 140. Male, wing, 55; tail, 63; culmen from base, 15; bill from nostril, 9; tarsus, 24. Female, wing, 52; tail, 60; culmen from base, 14; bill from nostril, 8; tarsus, 23.

Although this species resembles H. minutus both in size and color, it might be placed in another genus. The tail is decidedly longer than the wing, the latter rounded and weak; the first primary is equal to two-thirds of second and one-half of third; the fifth and sixth are nearly equal and longest. The plumage is somewhat decomposed and is less compact than in H. minutus.

Genus PHYLLERGATES Sharpe, 1883.

In size and superficial appearance Phyllergates resembles Orthotomus, but the two genera are really very distinct. In Phyllergates the bill is much wider and more depressed at the base, and blunter at the tip; the rictal bristles are slightly longer; the wing is longer; the tarsus and feet are more slender; the rectrices are much wider, nearly uniform in length, except the short outermost pair, and but ten in number.

Species.
  • a1. Chin and throat white philippinus (p. 589)
  • a2. Chin and throat cinnamon heterolæmus (p. 589)

574. PHYLLERGATES PHILIPPINUS Hartert.
LUZON TAILOR WARBLER.
  • Phyllergates cinereicollis (not of Sharpe) Grant, Ibis (1894), 510; Whitehead, Ibis (1899), 221 (habits).
  • Phyllergates philippinus Hartert, Novit. Zool. (1897), 4, 517; Sharpe, Hand-List (1903), 4, 237; McGregor and Worcester, Hand-List (1906), 91.

Luzon (Whitehead, McGregor).

Adult.—Forehead and crown cadmium-yellow; occiput and neck slate-gray; a line of lemon-yellow over eye; remainder of upper parts, including edges of the wing-feathers and rectrices, olive-green; (rump lemon-yellow in the male); inner webs of primaries edged with white; lores and band behind eye dusky gray; ear-coverts, cheeks, chin, throat, and fore breast silky white; remainder of under parts, including edge of wing, axillars, and wing-lining, bright lemon-yellow. Bill dusky brown; base of lower mandible lighter; legs pale yellow; nails light brown. Length, about 115. Male, wing, 44; tail, 42; culmen from base, 16; bill from nostril, 9; tarsus, 18. Female, wing, 42; tail, 37; culmen from base, 15; bill from nostril, 10; tarsus, 18.

The Luzon tailor warbler is abundant in the Province of Benguet; its habits are similar to those of the lowland tailorbirds which it seems to replace in the mountains.

575. PHYLLERGATES HETEROLÆMUS Mearns.
MINDANAO TAILOR WARBLER.
  • Phyllergates heterolæmus Mearns, Proc. Biol. Soc. Wash. (1905), 18, 86; McGregor and Worcester, Hand-List, (1906), 91.
