Banggai Crow
Corvus unicolor
An entirely black, short-tailed, pale-eyed crow confined to the island of Peleng in the Banggai Islands. Occurs in groups within canopy of montane forest. Tail just barely extends beyond wingtips when perched. Shorter-tailed and shorter-billed than Slender-billed Crow, and shows a pale eye, unlike that species. Voice also differs. Song is a “whee-kew-kew-kew,” with a rasping note starting the series and higher-pitched, ascending whistles following.

Subtropical Doradito
Pseudocolopteryx acutipennis
A bright flycatcher found in marshes in the Andes from Colombia to Argentina. Yellow below and olive above, sometimes showing a hint of a dark mask and dull yellowish edges on the wing feathers. Distinctive in habitat, although could be confused with a female Masked Yellowthroat, which has a pinkish bill and legs. Forages singly or in pairs; can be difficult to see in dense marsh grasses. Mostly occurs from 1,000 to 3,500 m, but some appear to move into lowlands in the winter in southern part of range. Gives single nasal calls as well as a whirring noise produced by the wings.

Rennell Shrikebill
Clytorhynchus hamlini
A large orange-brown bird with a black mask and a long, slightly decurved grayish-blue bill. Note the pale tuft at the “armpit.” Found mainly in the dense, tangled understory of primary forest. Song is a repetitive series of wavering, mournful whistles.

Pale-billed Sicklebill
Drepanornis bruijnii
A large, long-billed bird of lowland forest. Brown upperparts with black head and grayish facial skin behind the eye. Note the curved, pale bill. Male has a black throat, sides and two small, hornlike tufts on the head. Female has pale underparts with dark barring. Similar to female Twelve-wired Bird-of-Paradise and Magnificent Riflebird, but female Pale-billed Sicklebill has a longer, thinner, more curved bill. One of several vocalizations, a descending series of low whistles, reminiscent of Common Potoo.
