Golden-crowned Woodpecker
Chloropicus xantholophus
A large, long-billed woodpecker with an olive back, a bold facial pattern, and heavily marked underparts. The crown is black in the female and yellow in the male, though this yellow patch can be difficult to see. Found in rainforest and secondary forest at low and middle elevations. Calls include a fast whinnying call, a sharp “kwip,” and a series of similar notes. Also gives a distinctive drum that lasts about 3 seconds, beginning fast and then slowing. Similar to Bearded and Fire-bellied Woodpeckers, but there is very little overlap in range; Golden-crowned can be separated from Bearded by the unbarred back and from Fire-bellied by the lack of a red belly. Males further distinguished by their yellow crown.
识别特征
The yellow-crested woodpecker grows to a length of 22 to 25 cm (9 to 10 in). The male has a small golden patch with black flecking on the crown, most noticeable in display, but the female lacks this. In other respects, the sexes are similar, the forehead being brown and the cheeks and throat whitish; there is a broad black streak through the eye which extends to the sides of the neck. The nape is black and the upper parts of the body are dull brownish-olive, usually plain but sometimes slightly barred. The rump and upper tail coverts are yellowish and the tail chocolate-brown. The underparts are brown with white spotting on the breast and white barring on the flanks and lower belly. The beak is long, the upper mandible being darker than the lower one, the iris is dark red and the legs and feet are olive-grey. Juveniles are somewhat drabber, with fewer spots but more barring, and both sexes have some yellow tipped feathers in the crown.

Mackinnon's Shrike
Lanius mackinnoni
Medium-sized, slim shrike patterned in dark gray, black, and white. The male has completely white underparts, while the female has a rufous flank patch. There are large white slashes across the shoulders. Found along forest edge and in forest clearings, lush woodland, cultivations, and gardens. Usually seen singly or in pairs. The song is a slow, highly varied series of many different types of notes, and can include imitations of other birds. Similar to Northern Fiscal, but has a gray crown and back. Distinguished from other black-masked, gray-backed shrikes by the lack of a white nick on the wing.
Tit-like Dacnis
Xenodacnis parina
Unique small tanager of high elevations. Favors Polylepis woodland, but also found in other humid forest edges and scrub. Males are deep, vibrant blue; females are orangey tan, with small blue patches on the head, wing, and tail. Most often found in small, single-species flocks. Song is a distinctive, explosive series of up- or down-slurred whistles mixed with buzzy hisses and rasps.
Pygmy Swiftlet
Collocalia troglodytes
A tiny, common swiftlet found over lowland forest. Gray below with a paler belly, a darker throat, and dark patches on the underside of the base of the forewing. Black above with a distinctive white band on the rump. Tail square, and dark under the base. Nests in caves, where it uses echolocation. Similar to Gray-rumped Swiftlet, but Pygmy is slightly smaller, with a cleaner white rump band. Gives grating calls in flight.
