White-tailed Iora
Aegithina nigrolutea
Also known as Marshall’s Iora. Very similar to Common Iora, but easily distinguished by the prominent white edges to the tail and the broad white edges to the tertials. Breeding males have with more prominent white on the flight feathers than Common Iora. The churring calls of White-tailed are subtly different than those of the Common Iora, and a trained ear can easily pick up this call even in places where the two species occur together. Unlike Common Iora, White-tailed is sparsely distributed, usually restricted to scrubby habitat with sparse acacia growth.

Anhinga
Anhinga anhinga
Long-necked “snake bird” found in wooded swamps, marshes, and ponds. Males are black with white on wing; females similar but with brownish neck and head. Dives underwater and spears fish with dagger-like bill. Often swims with only head and neck out of water. Like cormorants, perches out in the open to spread wings and dry feathers. Similar shape to cormorants but even longer-tailed with a more sharply pointed bill. Occasionally soars.
Pulitzer's Longbill
Macrosphenus pulitzeri
An unusual warbler with a long, straight bill and a pale eye. Mostly dull olive-green with a yellowish throat. Found locally along the Angolan escarpment in dry evergreen forest at low middle elevations, mainly in dense tangles at middle levels of the forest. Could be confused with camaropteras, but larger, without a bright green wing. Also similar to some greenbuls, but smaller and shorter-tailed. Usually detected by the distinctive song: a repeated, low-pitched, two-note “peet-treeya” phrase.
Quebracho Crested-Tinamou
Eudromia formosa
A striking tinamou of the northern chaco desert and scrub. Very similar to Elegant Crested-Tinamou, but range does not overlap. Prefers dense scrub and understory, but can also be seen in openings and roadsides. Voice distinctive, and quite different from Elegant Crested-Tinamou: two whistles that are each flat in pitch, then rising sharply in pitch at the end - “Tooooo-wee! Tooo-wee!”
