Timor Stubtail

Large black-and-white goshawk. Most individuals have a white breast, but some have almost completely black underparts. Immatures have dark streaks below, over a white or rusty base color. Found in forest, woodland, thick savanna, and plantations. Calls are a long wail and an agitated scolding series. Dark-breasted birds similar to dark-morph Gabar Goshawk and Ovambo Sparrowhawk but are larger and have yellow legs and base of the bill. Somewhat similar to hawk-eagles, but much longer-tailed and faster in flight.

Small, rather chunky but long-tailed bird of tropical forest and woodland in lowlands and foothills; endemic to western Mexico. Feeds at all levels, often at fruiting trees and bushes with other vireos and fruit-eating birds. Like most vireos, generally rather sluggish. Bright yellow-and-greenish plumage, plus cocked tail, strongly suggest smaller and more lightly built Wilson’s Warbler, but note the vireo’s broad pale eyebrow, stouter bill, and stronger blue-gray legs.

Enigmatic and distinctive, this compact all-dark martin has striking red eyes and a bright orange-red bill. Juvenile is duller. In lethargic flight it appears bulky-headed, short-tailed, and triangular-winged. Small to large groups forage high over forested rivers, swamps, and coastal scrub. Birds migrate between two breeding areas, one in coastal central Africa from Gabon to northern Angola (August to December), and another farther inland, centered on the Congo River in west-central Democratic Republic of Congo (January to May), but their habits remain poorly understood. Calls include a scratchy chattering “skeer-skeer”; large flocks can become cacophonous.
