Pallas's Sandgrouse
Syrrhaptes paradoxus
An unusual bird of dry plains and grasslands that looks like a cross between a dove and a grouse. Both sexes have a long, needle-thin tail, a rectangular black belly patch, and overall sandy-brown plumage. The male sports an orange-and-gray face and a pink tinge to his wings and back. The female is browner, with heavy speckling on the neck and nape. Flies in flocks, often gathering in groups of up to thousands strong at reliable waterholes.
识别特征
Pallas's sandgrouse is 30–41 cm (12–16 in) long with small, pigeon-like head and neck, but sturdy compact body. It has long pointed wings and tail and legs and toes are feathered. Its plumage is buff-coloured, barred above with a black belly patch and pale underwings. The black belly and pale underwing distinguish this species from the related Tibetan sandgrouse. The male Pallas's sandgrouse is distinguished by its grey head and breast, orange face and grey breast band. The female has duller plumage and lacks the breast band though it has more barring on the upperparts.<p>The small feet lack a hind toe, and the three front toes are fused together. The upper surface is feathered, and the underneath has a fleshy pad. The appearance of the foot is more like a paw than an avian foot.

分布与栖息地
This species breeds across middle latitudes of central Asia on dry steppes and similar habitats. Its nest is a ground scrape into which 2–3 greenish eggs with cryptic markings are laid.<p>It is a partial migrant, especially from the northern parts of its range in Kazakhstan and Mongolia, but the extent and distance of the southerly winter movement depends on the amount of snowfall.<p>Pallas's sandgrouse occasionally irrupts from its regular breeding and wintering range as a vagrant across Europe as far west as Great Britain, where it has bred, and Ireland. The reasons for these remarkable movements are not fully understood, but they have become less frequent, probably due to contraction of the western Siberian range as the steppes become more agricultural.

Versicolored Barbet
Eubucco versicolor
Brightly colored barbet of montane forest. Males are green with a yellow breast, a red belly band, and a red head; the color of the whisker can be blue or yellow depending on the subspecies. Females have a blue face and a greener body. Both sexes have a pale greenish-yellow bill. Often found singly or in pairs with mixed-species flocks, foraging in the mid-story and canopy of humid forest. Listen for a musical purr with a punctuated introductory note: “PA-prrrrr.”
Chattering Gnatwren
Ramphocaenus sticturus
Very small bird of humid tropical forest and edge. Favors vine tangles at mid-upper levels, where moves actively, holding its tail cocked and flopping it from side to side. Appearance is distinctive, with buffy face, very long thin bill, and fairly long tail with white tips. Similar to Long-billed Gnatwren but has three white spots on outer tail feathers and a slower, sometimes multiparted chattering song. Easily overlooked, but vocal.
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.
