Long-tailed Ground Dove
Uropelia campestris
Unmistakable ground dove. Brownish above and whitish below. Note the black spotting on the wings and the yellow eye-ring and legs. In flight the tail is V-shaped, with black sides and white tips. Found in grasslands and at the woodland edge, where it feeds on the ground. The song is a series of high-pitched “wha-ooop...wha-ooop...wha-ooop...” notes.
识别特征
The long-tailed ground dove is 15.7 to 17.7 cm (6.2 to 7.0 in) long. The adult male's forehead and crown are bluish gray. Its upperparts are brown with a pinkish tinge on the hindneck. The folded wing shows two iridescent purple bands and a row of large purplish black spots. The throat and breast are pinkish mauve fading to white on the belly. The long tail's central feathers are brown and the outer ones black with white tips. The eye is gray to blue surrounded by bare yellow to orange skin. The adult female's eye surround is paler than the male's; its underparts are paler pink, its hindneck and shoulders more olive-brown, and the rest of the upperparts an ashier gray. Juveniles are duller and more grayish brown overall, and the bands and spots on the wings are chestnut and buff.
分类信息
The long-tailed ground dove is the only member of its genus. It shares characteristics with both Columbina and Claravis doves but cannot be placed definitively in either. It is monotypic according to the International Ornithological Committee (IOC) and Clements taxonomies, but the Handbook of the Birds of the World adds subspecies U. c. figginsi to the nominate.

Chestnut-backed Sparrow-Weaver
Plocepasser rufoscapulatus
Large and distinctive weaver. Note the pale bill, bold head pattern, rufous back, and white wingbars. Found locally in miombo broadleaf woodland. Quiet and inconspicuous bird that feeds on the ground but often perches up in trees. The most common vocalization is a loose, metallic trill. Somewhat like White-browed Sparrow-Weaver, but easily separated by pale bill, striped head pattern, and rufous back.
Olive-backed Foliage-gleaner
Automolus infuscatus
Dark brown foliage-gleaner of mature rainforest understory. Warm dark brown body, with a clean whitish throat patch and reddish brown tail. Does not have prominent reddish brown in the wings like many other foliage-gleaners do; the clean whitish throat, plain face (without a strong eyebrow) and habit of foraging low are other good distinguishing features to tell it apart from other foliage-gleaners. Primarily found in the understory of mature rainforest. Listen for its song, a musical trill with stuttered introductory note, “ch-trrrrrrrr”, similar to that of Chestnut-crowned Foliage-gleaner from denser secondary growth habitats, but slightly lower and with a more distinct introductory note.
Lesser Shrike-Tyrant
Agriornis murinus
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.
