Eastern Plantain-eater

A nest parasite that lays its eggs in the nests of African and Black-bellied Firefinches and Brown and Dybowski's Twinspots. Breeding males are glossy black with blue iridescence and a pale brownish panel in the wings. Females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The bill is whitish and the legs very pale purplish. Found locally in lush woodland, savanna, and cultivated areas. Given current knowledge, can only be confidently identified by mimicked vocalizations. Each male parasitizes only one of the four host species and imitates its vocalizations, often mixing them into a scratchy jumble of high-pitched notes. 

A small brown owl with yellow eyes and feathered ear tufts. Note square head shape when tufts are not raised. Body all brown with extensive scattered darker and paler markings. Juvenile is heavily barred on the back and crown. Endemic to the Banggai islands off the east coast of Sulawesi; known specifically from Peleng and Labobo. Inhabits understory of forest and forest edge from lowlands to lower mountains. Distinctive: the only scops-owl in range. Song is a short, low trill, quite different from the clipped whistle of Sulawesi Scops-Owl, which it was once regarded as a subspecies of.

Elusive brown skulker with a pale throat and gray face. Dark edges to its back and crown feathers give it a scaly-looking quality. Forages on ground and in undergrowth, almost always under heavy cover and rarely emerging into the open. Extremely similar in appearance to Pale-throated, Chin Hills, and Long-tailed wren-babblers, but no range overlap. Song is a long ascending trill with a stuttering, bubbly quality to it.
