White-striped Warbler

A large gray cuckooshrike with a strong, hooked bill. Upperparts are mostly gray with black primaries; male darker than female. Note pale patch on back and white tail tips when bird is in flight. Male is gray with a lightly barred white belly. Female has denser barring that transitions to a white lower belly and undertail. Both sexes have a dark patch from the bill to slightly behind the eye, giving a masked impression. Juvenile is brownish, heavily scaled with whitish-buff, and mottled on the underparts. Immature has broader white edges to wing feathers. Vocal. Often gives a two-noted, rather nasal “gii-yaak,” uttered in flight as well as from a perch; also gives scratchy squeal calls. Inhabits lightly wooded country, avoiding wet forests.

Small cuckooshrike with a restricted range, found only in the Banggai Archipelago, east of Sulawesi. Males are mainly gray with black on the face, wing, and tail. Distinctive female is mostly rufous-brown, with unmarked buffy underparts. Found in forest and forest edge habitats. Vocalizations poorly known, but include downslurred whistles, sometimes given in pairs. Distinctive within its small range.

Medium-sized, typical nightjar with bold pale spots on the back. Both sexes have a broad pale patch on the outer tail that is white in males and buff in females. Found in a variety of woodland and savanna habitats that are usually moist and often near water. Song is an extraordinarily long, dry trill that changes in speed and pitch. Most similar to Swamp Nightjar, but has smaller pale patches in the outer tail and lacks a blackish cheek; male has a white trailing edge to the wing in flight. Also similar to Montane Nightjar but found in different habitat.
