Pied-crested Tit-Tyrant

Dark, burly medium-sized ibis. Restricted pale patches on the nape and shoulder distinguish this from all-dark ibises. Habitat preferences differ somewhat in two parts of disjunct range; Bornean birds favor mature riparian forests, while Indochinese birds are generally found in wet or flooded openings in dry forest and wooded plains. Forages singly, in pairs, or in small groups. Often disperses with the arrival of seasonal rains. Gives loud, resonating honks and croaking roars. Declining across range; status of Bornean population especially tenuous.

Dull brown babbler with yellowish-tinged underparts, a faintly gray face, and a warmer orange-brown crown. Throat and chest are faintly streaked, but not as evident as that of the very similar Pin-striped Tit-Babbler, from which Gray-faced can also be distinguished by its grayer face and less contrast between the more warmly-colored crown and duller upperparts. Forages in noisy flocks in the middle and lower levels of the forest. Ranges from lowlands up into the foothills. Mellow-sounding song contrasts with rather nasal, chattering calls.

Large antbird with a very distinctive, robust upturned bill. Males are all black and females are chestnut with a black throat patch. An apparently naturally rare inhabitant of the dense understory of humid forests, where it forages at lower levels, favoring areas with Lepidocaryum palms. The song is a series of musical whistles “tree-tree-tree,” repeated for long periods.
