Oriole Finch

Small, strikingly-plumaged antbird with a long tail and a very restricted range. Inhabits the understory of low stature or regenerating forests, forest edges, scrub, and abandoned plantations where it is very active and occasionally joins mixed-species flocks. Much plumage variation, with coastal males near Rio de Janeiro (formerly split as Restinga Antwren) being almost uniformly sooty-black with only slightly grayer back and spotted white wingbars. Two more northerly subspecies vary between rufous-brown and dark gray above, but both are black below with a bold white eyebrow and white wing spots. In all subspecies, females are pale whitish below and brown above with a bold white eyebrow. Male song is a monotonous series of harsh chip notes; female gives nasal squeaks.

A distinctive species with fine zebra-striped plumage and a long and shovel-shaped bill giving a fang-like appearance. Typically feeds by swimming in tight circles. Like many waterbirds in inland Australia, it moves around a lot, and can be found in very large numbers when conditions are right.

Compact songbird with short bill. Males in much of range are olive above, yellow below, with white throat set in black head; males and females on Norfolk Island are olive-brown with yellowish underparts (brightest on undertail). Females vary across range, with eastern birds having some amount of yellow on the underparts and western birds (formerly treated as full species, “Western Whistler”) being gray-brown above and pale below, lacking yellow. Olive Whistler much browner below, with well-defined whitish bib. Inhabits a great variety of habitats. Bright, whistled song varies, but often has a whip-like ending.
