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.
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
The black-headed bunting is found in flocks as it forages on grasslands for seeds. They breed in summer, building a nest in a low bush or on the ground. The nest is a cup made of dry grass and lined with hair. The clutch consists of four to six eggs. The eggs hatch after about 13 days and the chicks fledge after about 10 days. Its natural food consists of insects when feeding young, and otherwise seeds. In Bulgaria, the collapse of the drying cotton thistle (Onopordum acanthium) stems on which the birds build their nests has caused high mortality; this is thought to be an example of anecological trap. In northern Iran, there is a region of range overlap with the red-headed bunting and natural hybrids are common although molecular data indicates that there is considerable genetic divergence between the two species.
Like the red-headed bunting but unlike many other Emberiza buntings, it has two moults in a year. It undergoes one moult in the winter quarters prior to migrating back to the breeding region, and another after breeding. Young birds fledge with a soft plumage and then moult into a juvenile plumage before migrating and then assume an adult plumage after moulting in their winter quarters.
In winter their call is a single note tweet or soft zrit. The song consists of a loud series of strophes each made up a high harsh notes that accelerate into a jangling mix with some clear slurred notes interspersed before stopping abruptly.From Wikipedia, the free encyclopedia
