Green-billed Malkoha

Medium-sized harrier, flies with wings held in a V-shape, low over open fields and marshes, listening for rodents lurking below. Distinctive foraging behavior and conspicuous white patch on rump in all plumages. Five long primary ‘finger tips’ prominent in flight. Females and immatures are warm brown with streaky breasts. Adult male has plain mid-gray wings with black wingtips and paler belly.

A small yuhina of open forest environments. Black chin is not very noticeable, but the black crest is. Body is brown above and light tan below. Surprisingly noticeable bright red bill base is unique amongst yuhinas. Forages in the upper levels, where it gives a buzzy chatter and a ringing, repetitive song composed of high whistles.

Small, warbler-like flycatcher found in the Andes and coastal hills. Mostly gray and white with whitish wingbars, white eyebrow, and rufous wing patches. Similar to Rufous-winged Antwren but lacks yellow on belly and has a gray crown. Actively forages at middle to upper levels of forest, and may join mixed-species flocks. Gives quiet but sharp notes, either alone or in a short series. Erratic in its occurrence and may seemingly be absent from some sites for months at a time; its movements have not been studied extensively.
