Cape Barren Goose

Brightly-colored swallow with a deeply forked tail, pale orangish rump, black squared-off undertail coverts, an incomplete orange collar, and faint streaking below. Juveniles average paler and lack extensive orangish tones; may resemble house-martins but note deeply forked tail. Typically glides on stiff, flat wings, flying quite languidly with shallow wingbeats. Builds mud nests in mountains, on sea cliffs, and on buildings and other structures. Forages over open areas. Frequently gives a short, sparrow-like “twi’wit.” Very similar to African Red-rumped Swallow, but shows much heavier streaking below.

Active little bird with a chocolate-brown chest and a bright white collar. Forages in the lower and middle levels of foothill and montane forest in flocks, often with other species. Overall brownish coloration distinguishes it from similar small tits and bushtits. Like other bushtits, can often be inquisitive and confiding. Gives a trio of high, thin whistles, as well as occasional chatters and trills.

Small sparrow found in lowlands and foothills from northern Argentina to southeastern Bolivia. It has chestnut and gray stripes on the head and faint black and white mustache streaks. Similar to Yungas Sparrow, with which it was formerly lumped as Stripe-capped Sparrow, but is smaller with less black between the eye and bill, browner wings, and different voice. Inhabits open, grassy habitats with scattered trees and low scrub. Song is a fairly rapid series of sweet whistles, repeated every few seconds.
