Red-headed Bunting

The red-headed bunting is about 17 centimetres long, with a robust grey bill and a long tail. Breeding males have bright yellow underparts and rump, a greenish streaked back, greyish-brown wing bars, and a chestnut-red head and breast. Females are a faded version of the males, with paler yellow underparts, a grey-brown back and a greyish head. Juveniles resemble females, and both are similar to those of the black-headed bunting and hard to tell apart. (Spanish Wikipedia, general species account)

It is a migrant that breeds in central Asia, in Afghanistan, Iran, Kazakhstan, Kyrgyzstan, Mongolia, Tajikistan, Turkmenistan, Uzbekistan and China, and moves to India and Bangladesh for the winter. It breeds in open scrubland, including farmland, building its nest in trees or bushes and usually laying three to five eggs. It feeds on seeds and insects, the latter especially while breeding. In western Europe records of this vagrant are confused by escaped cage birds. (Spanish Wikipedia and English Wikipedia, general species account)
