Chestnut-backed Buttonquail

A medium-sized dusky bird that prefers moist montane forests, but can be also found in most wooded areas with dense vegetation. Feeds in trees and on the ground. Its namesake white eye is distinctive, but its bright broken white throat collar, contrasting so markedly with its dark plumage, is also unique. Shier than the somewhat similar White-chinned Thrush, which has a dark eye, orange bill and legs, and lacks a white collar. The White-eyed Thrush’s song is a long series of highly variable, repeated phrases (phrases most often repeated thrice, but commonly from two to five times). Calls include a plaintive whistled “weee-woooo,” with the first note slightly higher and a quick, almost ducklike “yak.”

A medium-sized bird of montane forest and secondary habitat in the Baliem Valley. Typical male “golden” whistler, with yellow belly, black head and breast band, and a white throat. Female has a brown head and breast band with a scaled throat. Co-occurs with the similar Sclater’s Whistler, but Baliem male has a broad yellow band around the back of the neck, and female has a scaled rather than plain white throat. A jumbled, whistled song containing some notes with an explosive quality.

Large, heavy-billed woodcreeper. Has rather unmarked plumage, but note the buffy eyebrow, moustachial stripe, and throat. No other woodcreeper within its range has such a large, strong bill. Inhabits deciduous dry forests and wooded caatinga. Song is a whining series of unmelodic notes, such as “nk-wiirh, week! weeer, weeer, weeur, weuur.”
