Sulawesi Drongo

Fairly large storm-petrel; overall dark blackish-brown with rather narrow white rump band that wraps around the sides. Typical flight style powerful and fairly direct, often with long glides and high, smooth arcs. Pale band on upperwing is typically faint and does not extend to the leading edge of the wing. Uncommon in deep, warm water in the Atlantic and Pacific Oceans; complex and very subtle variation across range. Probably comprises multiple different species. Most similar to Wilson's and Leach's Storm-Petrels, but note squared-off tail (sometimes with a very shallow notch), weaker upperwing bar, long wings, and more direct flight with smooth turns (less jolting than Leach's and less fluttery than Wilson's).

A gregarious brown babbler with a striking yellow-orange eye that is rimmed with red in the southern part of its range. It has a multitude of tiny white chevrons on the head and breast that are diagnostic. Groups occupy woodland and savanna, foraging for insects, spiders, and small vertebrates on the ground or in low shrubs and trees. This is the main host species for the nest parasite Levaillant’s Cuckoo. A dry gurgling babble “gra-gra-gra-gra-gra” is given by multiple birds, keeping the group together.

Small finch-like bird of lowland rainforest. Male is glossy navy blue with a deep red-orange belly, fairly distinctive in its range; female is golden with gray wash on the head, back, and belly, and orange-red undertail coverts. Females similar to females of Orange-bellied Euphonia, but usually have deeper orange or red undertail coverts (not yellow). Found in humid forests, where often one of the most common euphonias. Frequently heard giving a rapid, deep chatter “chree-chree-chree-chree.”
