White-billed Buffalo-Weaver

White-billed Buffalo-Weaver

Bubalornis albirostris

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. 

Rose-crowned Fruit-Dove

Rose-crowned Fruit-Dove

Ptilinopus regina

Tiny green and yellow dove. Yellow-orange belly and vent (note Superb Fruit-Dove has a white belly and vent). Pink forehead, gray face and neck, and often a pinkish area on upper belly. Found in rainforests, but also in coastal vine forest. This species calls frequently, and typically with a long series of gradually accelerating notes.

Antioquia Bristle-Tyrant

Antioquia Bristle-Tyrant

Pogonotriccus lanyoni

Rare flycatcher known only from a few sites in the Colombian Andes, mainly in the northern part of the central range. It is fairly small and mostly yellow, with a gray crown and broad, yellow wingbars. Yellow and gray smudges on ears can be very indistinct. Often confused with the much more common Yellow-olive Flycatcher, but bill is narrower, wingbars are brighter yellow, and voice is different. Typical song is a short burst that starts off as a dry rattle and then morphs into airy squeaking. Inhabits humid forest and sometimes joins mixed species flocks.
