Black-faced Waxbill

Old World oriole with mostly yellow plumage, a dull-green hood, and a red bill. Found in forest, forest edge, lush woodland, and adjacent secondary habitats, at low and middle elevations. Song is a series of slurred, liquid whistles, and calls include a raspy, up-slurred whine. Similar to African Black-headed Oriole, but with a good view, easily separated by the green rather than black hood. Often found in the same areas as Eurasian Golden and African Golden Orioles, but distinguished by being hooded rather than yellow-headed.

Small (and small-billed) shrike-tyrant of open country in the southern cone, more reminiscent of a monjita than a shrike-tyrant. Note small bill, lacking terminal hook. Breeds in northern Patagonia and the southern Monte desert, as well as the Sierra de Comenchingones in central Argentina. Disperses northward and upslope into W Paraguay and SE Bolivia during the austral winter. Prefers exposed perches in low vegetation, wires, and shrubs.

A common, medium-sized honeyeater of all wooded habitats in the lowlands and foothills. Olive plumage, a little paler on the underparts with no mottling. Large and elongated, yellow ear spot. ID problematic as it co-occurs with many other similar species. Mountain and Graceful are smaller, Puff-backed has a thicker bill, Yellow-gaped has a more prominent yellow gape. Calls include a trill, a whistle and a “chup!”.
