Black-headed bunting : ウィキペディア英語版 | Black-headed bunting
The black-headed bunting (''Emberiza melanocephala'') is a passerine bird in the bunting family Emberizidae. It breeds in south-east Europe east to Iran and migrates in winter mainly to India, with some individuals moving further into south-east Asia. Like others in its family, it is found in open grassland habitats where they fly in flocks in search of grains and seed. Adult males are well marked with yellow underparts, chestnut back and a black head. Adult females in breeding plumage look like duller males. In other plumages, they can be hard to separate from the closely related red-headed bunting and natural hybridization occurs between the two species in the zone of overlap of their breeding ranges in northern Iran. ==Description== This bird is 15 cm long, larger than reed bunting, and long-tailed. The breeding male has bright yellow underparts, chestnut upperparts and a black hood. The female is a washed-out version of the male, with paler underparts, a grey-brown back and a greyish head. The juvenile is similar but the vent is yellow, and both can be difficult to separate from the corresponding plumages of the closely related red-headed bunting although the black-headed tends to have the cheeks darker than the throat. First year males have a grey crown and the back has patches of chestnut and grey. First year females can be difficult to separate from female red-headed buntings although having more streaking on the crown than on the lower back. The vent is yellow. The black- and red-headed buntings represent sister species which forms a clade along with the crested bunting.
