Roll's Partridge
Arborophila rolli
Restricted to montane and foothill broadleaf forests between 500 and 2000 meters in the Batak Highlands of northern Sumatra. Forages in dense vegetation on the forest floor, often pairs, but also singly and in small groups. More easily heard than seen; listen for its song, a rapid and seemingly endless series of steadily rising hooting whistles. Pairs often duet. If seen, note the bright white cheek patch, black head, and black-and-brown-striped body; also note the bright red patch of bare skin around the eye, and curved black-and-white streaks running down the sides. Vocalizations and appearance similar to Sumatran Partridge, but separated by range and present species’ warm brown breast and more extensive white on the face.

Similar to Tropical Boubou, but barely overlaps in range and lacks a white shoulder patch. Also similar to the smaller Black-backed Puffback, but separated by the lack of white on the upperparts. Has a diverse range of vocalizations, including a hollow rising whistle, up-and-down “laser gun” notes, rasps, and croaks, often delivered in a duet by a pair.

Todirostrum chrysocrotaphum
Tiny, boldly colored flycatcher of lowland rainforest. Black and yellow with a boat-shaped bill. Found in the canopy of mature rainforest, often in upland areas; occasionally also found around forest edges, including sometimes around gardens and human dwellings.
