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.

White-breasted Waterhen
Amaurornis phoenicurus
Medium-sized, fairly common chickenlike marsh bird found in meadows, ditches, riversides, marshes, as well as parks and farmlands in close proximity to humans; often seen foraging in the open. Adults are dark slaty above and white below, with a rusty patch under the tail. Juvenile similar but duller in color. Remarkably variable song is a series of hooting, grunting, or rasping notes or phrases, repeated monotonously, often from an exposed perch.
Chiriqui Foliage-gleaner
Automolus exsertus
Skulking and generally inconspicuous brown bird of humid tropical forest. Found as singles or pairs, clambering in vine tangles or other dense understory, at times in leaf litter on the forest floor; usually difficult to see clearly. Note the rich buffy throat, broad eyebrow, and the dark rusty tail on an otherwise dark brownish bird. Loud song is a repeated, churring rattle, given from middle level perches inside the forest.
Choco Brushfinch
Atlapetes crassus
This chunky bird is dingy yellow below and dark brownish above with a tawny crown. Sexes similar. Could be confused with Yellow-breasted Brushfinch, which is found at higher elevations and has a brighter rufous crown. Pairs or small groups are found foraging in the lower levels of montane forest, edges and tangles, often clambering around a couple meters from the ground. Found from around 600–2,500 m.
