Rüppell's Bustard
Heterotetrax rueppelii
Small, pale, desert-dwelling bustard. Males have a bolder pattern of black, gray, and white on the face, though both sexes show a black stripe down the throat. Found in open desert and semi-desert, both in grassy areas and virtually barren gravel or sand flats. Usually in pairs. Call is a weirdly frog-like duet. Overlaps slightly with Karoo Bustard in southern Namibia, but easily separated by bolder face pattern and black stripe down the neck.

Malagasy Brush-Warbler
Nesillas typica
Medium-sized brown bird with a long, spiky tail. Found in a wide variety of moist and woody habitats, including rainforest, wet scrub, plantations, and gardens. Absent or very local in much of west and southwest Madagascar. Skulks in thick undergrowth. Incessantly given call is a Geiger counter-like ticking. Darker brown than Subdesert Brush-Warbler, with a lower-pitched call and little overlap in range. Similar to Madagascar Swamp-Warbler, but has less distinct breast streaking and white eyebrow, and is generally found in scrub rather than marsh.

Black-backed Oriole
Icterus abeillei
Attractive orange-and-black oriole endemic to central Mexico, where it takes the place of Bullock’s Oriole (of western North America). Favors open woods, plantations, hedges with tall trees, and towns; migrants also occur in pine-oak forest in mountains. Feeds at all levels in trees and bushes, mixing readily with other orioles. Yellow-orange plumage of male distinct from purer orange of other orioles; also note the big white wing panel, black nape and cheeks, and black flanks. Female very similar to female Bullock’s Oriole but shows ghosting of male head pattern.

Philby's Partridge
Alectoris philbyi
Handsome partridge of the southwest Arabian mountains. Mostly pale gray and tan, with chestnut-and-white slashes along the sides, and a black face mask. In flight, shows dark wingtips and chestnut sides to the tail. Found in dry, rocky habitat at middle and high elevations, with a preference for bush areas. The common vocalization, given mainly early and late in the day, is an emphatic series of “chuk-chek-chuk” calls. Also gives clucking calls, especially when flushed. Similar to Arabian Partridge, but distinguished by the black face mask, and when in flight, by the chestnut in the tail.
