Sulawesi Hawk-Eagle

Small bird with thin bill that is more substantial than most other gerygones’. Upperparts brown, underparts off-white, with pale broken eyering and bright red eye. Juvenile lacks red eye and has yellow gape (base of bill). Similar Mangrove Gerygone has smaller bill, no split eyering, and a more delicate, less frantic song; Brown Gerygone has a smaller bill, unmusical "which-is-it" song. Inhabits mangroves, thick riparian vegetation.

A critically endangered Galápagos finch found only on the island of Floreana. Bill is moderately curved on both upper and lower edges, and slightly longer than it is deep. Male has a black hood, brownish-olive upperparts, and a pale belly. Female is tan with whitish underparts. Both sexes have faint streaking on the breast. Bill is black on breeding male and orange on female and non-breeding male. Large Tree-Finch has larger and more bulbous bill. Small Tree-Finch has slightly smaller bill and body. Identification is much easier when more than one species is present to allow direct comparison. Medium Tree-Finch inhabits forest mainly in the highlands but is occasionally seen closer to the coast, where it may be only a seasonal visitor.

Medium-sized odd-looking, ground-walking flycatcher of humid forests and second growth. Unmistakable in most of its range with its olive-brown back, yellow bill, white face and belly, and black breast. Told from Ringed Antpipit, for which there is barely any distributional overlap, by being paler and less olive above with a creamier chin and throat. Generally shy but its song is very distinct: a melodic series of explosive “preeeh-prrrwee-prurr-prii” notes. Also makes loud bill-snapping noises.
