White-billed Starling

A lithe, medium-sized bustard with black daubs on a mostly tan-colored back. The male has a black belly, neck stripe, throat, and face patch. The female is uniform buff-brown from the belly to the head. In flight, both sexes have white windows in the wings. Singles and pairs inhabit tall grassland and grassy savanna. Its strange display involves the male stretching his neck and making a frog-like “kwoork” croak, and as he retracts his head to the shoulders, follows with a “grrrr” growl and champagne-cork-like “pop” while his head lifts again. He also performs an aerial display with the wings held back rigidly and with a puffed throat exposed.

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.

Streaky canopy foliage-gleaner with a slightly hooked bill tip. Light buffy brown overall with extensive streaking from the head down to the back and breast, with reddish wings and tail. Forages in the midstory and canopy with mixed species flocks, keeping its body horizontal as it clambers along branches. Most common in upland forest, where it can be the most common foliage-gleaner in canopy mixed species flocks, but can also occasionally be found in mature forest in seasonally flooded areas.
