Black-headed Greenfinch

A big, bulky, long-tailed black weaver. The bill is white in males and black in females. There is a white patch on the front edge of the shoulder, and also a pale patch in the wing that can be conspicuous in flight. Immatures are dark brown with heavy streaking below. Found in dry savanna and woodland, often in flocks. Builds huge communal stick nests. Similar to Red-billed Buffalo-Weaver, but never shows a red bill. The common call is a harsh “sjet” that is often given repeatedly by a whole group in chorus. 

Colorful miniature waterfowl that is smaller than most ducks. Both sexes have rufous underparts, a dark back, white on the face, and white on the wing in flight. Males have a green patch on the back of the head and a yellow bill; females have a black-and-white head and a dark bill. Found in freshwater wetlands with floating vegetation, especially water lilies. Shy and inconspicuous, as it generally avoids open water. Voice is a high-pitched squeaking. Small size and bold and colorful plumage separate it from other waterfowl.

Flowerpiercers have a unique upturned bill with a sharp hook at the tip; they use it to pierce the bases of flowers to extract nectar. The bill shape alone is enough to identify Slaty Flowerpiercer in its range; also note male’s uniform blue-gray plumage. Female is dull brown. Found in mountains above 1300m, usually in pairs foraging in bushes at the forest edge, shrubby second growth, and gardens.
