Green Jery

Big, spectacular, black-and-white hornbill. The males have a large black-and-white bill, and females a much smaller all-dark one. In flight, shows a broad white patch at the back of the wing and a black tail with white sides. Found in thick forest and adjacent areas of lush woodland and cultivation. Usually in pairs or small groups. The loud calls are honking and yapping notes that are often given in a quick series. Similar to White-thighed and Brown-cheeked Hornbills, but has a black center to the tail, and the wingtips are black. Also has a darker bill and casque than those species.

A tiny puffball of feathers that looks like a bumblebee crossed with a down pillow. Minute size and compact shape prevent confusion with most other species, but also note the faint dusky streaking on whitish underparts, indistinct black crescent behind the eye, and olive-yellow upperparts. Found in both secondary and primary humid woodland, but can be difficult to spot as it moves in the canopy of tall trees. Its song is an easily overlooked, insect-like short, fast trill that accelerates into a buzz.

Bulky and sluggish inhabitant of Sumatra’s highland forests. Resembles a cross between a large thrush and a small crow; both sexes are glossy black with an electric-blue tail, wing panel, and crown. Males have a dark face, whereas females have a buffy one. Dull naked red skin around the eye can be evident at close range. Like other cochoas, its inactive habits can make this species difficult to see as it perches up in dense vegetation. Song is a haunting mournful whistle.
