The pied wheatear (''Oenanthe pleschanka'') is a wheatear, a small insectivorous passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher (family Muscicapidae). This migratory central Asiatic wheatear occurs from the extreme southeast of Europe to China, and has been found wintering in India and northeastern Africa. It is a very rare vagrant to western Europe. The male is a boldly marked white-and-black bird. The white crown tinged with brown contrasts with the black face and throat and white rump. The female is browner, and the head is washed with sandy buff. Females are darker than the females of the northern wheatear, look smaller and show less white on the rump. The tail feathers are white with characteristic black markings, which form an inverted black "T" pattern that resembles the tail of the black-eared wheatear. This bird nests in open, stony, sparsely vegetated regions, laying four to six eggs in a hole, under a stone or in a rock crevice. The pied wheatear primarily eats insects but will also take seeds. ==Description== 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 . 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.〔 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.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pied wheatear」の詳細全文を読む スポンサード リンク
