Adult.--Very similar to Collocalia whiteheadi but the tarsi distinctly feathered. Hartert gives the following description and measurements: "Upper surface dark sooty brown with very little gloss; head, wings, and tail darker and more glossy; feathers in front of the eye whitish with dark brown tips; lower surface brownish gray with darker shaft-stripes; under wing-coverts blackish brown. Total length, about 114; bill at base, 4; wing, 112 to 119; tail, 56. The young bird is like the adult in plumage." (Hartert.)

"Two males measure, 120 in length; wing, 107; tail, 46; culmen, 6; tarsus, 7; middle toe with claw, 9. Two females: Wing, 116; tail, 48; culmen, 6; tarsus, 10; middle toe with claw, 7. Bill, feet, and nails black, legs light brown." (Bourns and Worcester MS.)

Adult.--Similar to Collocalia whiteheadi but easily recognized by the whitish or smoky gray band across rump; shafts of rump-feathers darker; tarsi unfeathered.

Young.--Probably the young bird is much like the adult, as with other species of the genus.

"Four males from Culion measure, 112 in length; wing, 115; tail, 50; culmen, 5; tarsus, 9; middle toe with claw, 9. Iris dark brown; legs and feet light brown; bill and nails black." (Bourns and Worcester MS.)

Adult.--Above glossy black, bases of feathers smoky brown; across the rump a white band 5 mm. wide, the shaft of each feather dusky; chin and sides of face and neck dusky brown; feathers in front of eye white with dusky tips; feathers of throat, breast, and abdomen with white tips and dusky bases and shaft-lines, producing a mottled appearance, the white predominating on the abdomen; under tail-coverts glossy black.

"Very common throughout the Islands. Builds edible nests. Nests always in caves, and composed chiefly or entirely of secretion from the mouths of the birds. When the birds are persistently robbed, however, they seem to become discouraged, and mix in grass, stems of small plants, moss, etc. Two or three white eggs are deposited. They measure: 15.2 to 17.7 by 10.1 to 10.9. Fourteen males from Siquijor average, 92 in length; wing, 92; tail, 41; culmen, 4; tarsus, 8; middle toe with claw, 9. Bill, legs, and feet black." (Bourns and Worcester MS.)

Ni-do and sa-lum-pi-ping-ao, Calayan.

Adult.--Above very dark glossy green, short upper tail-coverts margined with pure white; feathers in front of eye white with dusky tips; sides of head, neck, and chin mouse-gray; feathers of throat with narrow white edges, posteriorly the white edges gradually increase in width so that the abdomen is almost entirely white; under tail-coverts dark glossy green with narrow white margins; under wing-coverts narrowly edged with white. Iris, bill, toes, and nails black; tarsi dark flesh. Length, about 96. Five specimens of each sex from Calayan measure: Males, wing, 102 to 107; tail, 40 to 46; females, wing, 102 to 105; tail, 41 to 42.

Young.--Two nestlings from Sibuyan are like the adult in plumage except that the white edges to the upper tail-coverts are but just indicated. Bill and nails black; legs pale flesh.

Nest.--Nests in small colonies, fastening the nests to the face of a rock. The nest is composed of blackish brown hair-moss and held together by the characteristic glutenous saliva. The eggs do not differ from others of this genus being two in number and pure white in color. The eggs of a set collected in Sibuyan, June 11, 1904, measure 18.2 by 10.9 and 17 by 11.6 mm.

This species has been very rare in collections; the only specimen in the British Museum in 1892 was a skin of doubtful locality collected by von Othberg. We have met with it on several islands; in Sibuyan and Calayan it was extremely abundant.
