Bornean Ground-Cuckoo

A tall, dome-headed, plover-like bird with large, yellow eyes. Mostly brownish in color, it has a grayish wing panel that is bordered above with a narrow white bar. This thick-knee never wanders far from permanent water. It is crepuscular and nocturnal; early evenings are often punctuated by its distinctive, high-pitched, piping calls that speed up then slow down. The similar Senegal Thick-knee differs by having a gray wing panel bordered above with a black bar only. Spotted Thick-knee lacks the wing panel and has spots rather than streaks on the back.

Small, streaky antbird of humid forest along the east slope of the Andes; also found in lowlands away from the mountains in a few areas. Male is boldly striped with black and white. Female is black and tan with a similar stripy pattern but has plainer underparts. Inhabits dense vegetation at forest edge or overgrown clearings. Song is an excited series of doubled notes: “hiccup, hiccup, hiccup…”

Small bird of riverine and gallery forests in both forest and savanna regions; generally inconspicuous when not displaying. Adult male is distinctive with black body, sky-blue back, and red or yellow crown patch; both sexes have orange legs. Female is similar to White-bearded Manakin, but has somewhat slimmer shape and longer tail. Inhabits forest understory but may ascend to canopy, especially when displaying. Feeds on fruit like other manakins and may be seen at fruiting shrubs and trees. Often detected by loud, single call note; males produce a variety of bizarre sounds in coordinated group display.
