Yellow-throated Woodland-Warbler

Distinctive streaky brown bird of riverine habitats of the Orinoco Delta. Most of body brown with buffy streaks (tear-shaped on underparts). Rich chestnut on chin, wings, rump, and tail. Sexes similar. Locally common and often in pairs, found from understory to canopy in riverine forest where often climbs trunks like a woodcreeper. Voice is an explosive group of short notes, mostly in duet. Similar to Orinoco Softtail (no range overlap), which is less streaked and has a buff eyebrow; Rusty-backed Spinetail is unstreaked. Endemic to the Orinoco River of northeastern Venezuela.

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.

A typical thrush in shape and size, but with unusually dark coloration. Mostly blackish with a paler gray belly and yellow-orange bill, eye-ring, and legs. Females are slightly paler and show some mottled streaking on the throat and breast. Found locally in juniper and hagenia woodland in the mountains of northern Somalia. The vocalizations are poorly known, but it gives a typical thrush song and harsh “chk-chk” calls.
