Pied Wheatear
Oenanthe pleschanka
Jaunty little terrestrial songbird of plains, agricultural fields, and semi-desert, where often perches prominently on utility wires and boulders. Tuxedoed breeding male is black with snow-white crown, belly, and rump. Female is sandy brown above and white below. Nonbreeding adult and immature have sandy underparts and pale fringes to the wing feathers, producing a worn, scaly look. Note black-and-white tail pattern in all plumages. Circles and plunges in an impressive display flight, in which a rambling series of whistles, trills, and buzzes are given. Calls include twangy “bi-zee!”, dry “chak” notes, and short, falling “dew.”
识别特征
The crown, nape and neck of the adult male pied wheatear are pale brown, the feathers having pale tips and white bases. The mantle and scapulars are black with buff tips to the feathers. The back, rump and upper tail-coverts are creamy-white. The central pair of tail feathers are black with white bases but the rest are white with black tips, the outer pair having rather more black than the rest. There is a narrow buff-coloured line extending from the base of the beak to over the eye and the lores, ear coverts, chin, throat and upper breast are black. The rest of the breast is buff, the belly creamy-buff and the underwing coverts and axillaries are black tipped with white. The wing feathers are black with tips and edgings of creamy-buff. The bird moults in late summer and by the following year, the edges of the feathers are abraded and the crown and nape are white and the mantle, scapulars and wings black. The beak, legs and feet are black and the eyes dark brown. The length is about 5.75 inches (146 mm).<p>The adult female is similar to the male but the mantle and scapulars are brown with buff tips rather than black, the tail feathers are brown and white and the wing feathers brown with buff tips. Again, abrasion wears of the tips of the feathers and the bird becomes more uniformly brown and white with creamy buff underparts. The female is slightly smaller than the male. The juvenile is similar to the female but the feathers of the brown upperparts have pale centres near the tips giving the bird a speckled appearance.<p>The voice is a harsh zack zack. The song is low-pitched and musical and is performed by the male in early summer and again in August. It consists of a variable, imitative series of notes, sometimes lark-like and sometimes whistling, pouring out in a continual stream. It is sung from a perch on a rock or other high place or in the air during flight.

分布与栖息地
The pied wheatear is native to Southeast Europe and Western Asia. The breeding range extends from Romania and Bulgaria to Siberia, Altai and Mongolia and southwards to the Caucasus, Transcaspia, Turkestan, Iran and Afghanistan. It occurs at altitudes of up to 2,000 metres (6,600 ft) in the Altai and up to 3,000 metres (9,800 ft) in the Tien Shan.It migrates to Northeast Africa, passing through Southwest Asia on the way. In the breeding season it is found in rough open country, steppes with scant vegetation, stony slopes and hilly country. In its winter quarters it is found in similar locations with rock, scree and on plains with thorny scrub. It sometimes visits grassy areas and gardens. It has occurred as a vagrant in Italy, Heligoland and Scotland.

行为
The pied wheatear is rather shy but is conspicuous when spotted. It is not gregarious and single birds or pairs are found in rough, rocky countryside. It likes to perch on a bush or rock, alert and looking around and bobbing its tail up and down. When it spots a prey item it swoops down to the ground briefly to pick it up before returning to its perch. Its diet consists of small invertebrates such as ants, grasshoppers, beetles, flies and moths and their larvae, spiders and mites, and seeds are also eaten.

Abyssinian White-eye
Zosterops abyssinicus
A small, sharp-billed warbler-like bird. Note the yellow throat, gray underparts, and narrow white spectacles around the eyes. Found in woodland, montane forest edge, mangroves, gardens, and scrub. Usually in hyperactive flocks, often joining mixed-species flocks. Similar to Heuglin’s White-eye, and some individuals are difficult to separate, but generally shows a narrower eye-ring. Most common call is a high-pitched rising rattle. Song is a quiet, chatty sequence of “chew” notes.
Socotra Grosbeak
Rhynchostruthus socotranus
Handsome chunky gray-brown finch with a massive dark bill. Blackish hood, white ear-patches, and golden stripes in the dark wings and tail make this an easily recognizable species. Female has a paler, less well-defined hood than the male, and less yellow in the tail. Juvenile is buffier (including ear-patches) and more streaky overall. Singles, pairs and groups (up to 30) are a common endemic resident on Socotra, where it inhabits woodlands, dry scrubby rocky terrain, slopes, and riverbeds. Forages on the ground, as well as in trees, where they occasionally dangle by their feet, like parrots. Can be quite skittish. Song is a pleasant rolling series of sweet notes with an almost thrush-like quality. Call a quick whip-like "weet".
Bare-cheeked Trogon
Apaloderma aequatoriale
A trogon of lowland rainforests, almost always found in the forest interior, away from forest edges. Males and females have distinctive bare yellow facial skin below their eyes and between their eyes and bill. Both sexes have green backs and uppertails, red chests and vents, and finely barred wings. The species often calls motionless in the subcanopy, giving a series of 6-10 sad, descending coo notes, repeating these series 2-3 times per minute. Similar to the larger Narina Trogon, but Bare-cheeked Trogon is told apart by its song, its closed-canopy forest habitat, and the purely green tones on its head, back, and uppertail.
