Small-headed Elaenia

Medium-sized, grass-green toucan of humid tropical forest in foothills and highlands; also very locally in lowlands. Usually in pairs or small groups, moving through the canopy or feeding at fruiting trees. Nothing similar in its range. Note the rusty tail tips, best seen from below. Pattern of black and yellow on bill varies from region to region.

Its small head, very long, straight bill, and long tail give it a distinctive silhouette. Mostly dark brown above with a streaky crown and whitish belly. Usually perches upright on prominent perches in the top of trees at the forest edge or in riparian forests where they sally out to catch insects.

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.
