Black Lark
Melanocorypha yeltoniensis
Adult male is coal-black in worn plumage--unique amongst larks; in fresh plumage blackish feathers are edged in pale scaling. Female is duller and less distinctive: streaky gray-brown overall with a paler throat and belly and a stoutly pointed pinkish bill. Found in grassy steppe, particularly in areas interspersed with scattered shrubbery or wet patches; generally does not use agricultural lands, but can be found in association with domesticated livestock in the winter. Forages on the ground and flocks during colder months. Song is a long-winded series of drawn-out whistles, warbles, and chatters. Calls include various buzzy and squeaky notes.
识别特征
This is a large, robust lark, 18–20.5 cm (7.1–8.1 in) in length. The adult male is unmistakable, being all black with some pale feather fringes on its back, and with a yellowish or pink bill. The female is undistinguished in comparison, mainly dark-blotched grey above and paler below. Her legs and underwing are black.<p>The song is like a frantic version of that of Eurasian skylark.
分类信息
The black lark was originally placed in the genus Alauda. The current genus name is from Ancient Greek. Melanocorypha is from melas, "black", and koruphos a term used by ancient writers for a now unknown bird, but here confused with korudos, "lark". The specific yeltoniensis is from Lake Yelton in the Volgograd region of Russia.

分布与栖息地
This is a bird of open steppe, often near water. It is partially migratory, with birds from the northwest of its breeding range moving south-east to winter further into Russia and neighbouring countries, as far as the northern Black Sea coasts in southern Ukraine.<p>The black lark is a very rare vagrant away from its breeding range, with records during both spring and autumn passage periods, and also in winter; the following is a complete list of European records away from the breeding range and normal wintering range as of 2005.[citation needed]<p>An individual was also recorded on an unknown date (prior to 2003) in Lebanon.

Tropicoperdix charltonii
A shy partridge of tropical lowland rainforest. Brown with buff speckled upperparts, dark barring on the chest and sides, orange-brown belly, rusty bib, black speckled collar, and white, finely speckled throat. Uncommon and declining throughout its range. Forages in small flocks on the forest floor. Found at lower altitudes than other partridges in range and distinguished by its yellow legs and pale orange ear patch. Song, often given as a duet, consists of loud, tremulous whistles.
Bluish Flowerpiercer
Diglossa caerulescens
Dull blue-gray flowerpiercer found in the Andes from Venezuela to Bolivia. Dark reddish eye. Could be confused with Masked Flowerpiercer but duller overall without large black mask. Bill is less upswept than most flowerpiercers. Found singly or in pairs, often following a mixed-species flock through the forest canopy. Occurs from around 1,600-2,700m.
Song Thrush
Turdus philomelos
Plumage brown above and whitish below with droplet-shaped dark spots; breast has rich buffy wash in fresh plumage (mainly autumn–winter). Appreciably smaller, darker overall, and more compact than Mistle Thrush. An inhabitant of wooded habitats, including parks, gardens, and farmland with hedges and taller trees; often feeds on lawns and grassy verges, but usually near cover. Strident song, often heard in suburban neighborhoods, is more prolonged than that of Eurasian Blackbird, and frequently repeats phrases 2-4 times. A native of Eurasia, introduced to southeastern Australia, New Zealand, and a few surrounding islands.
