Chestnut Bunting

The chestnut bunting is a fairly small bunting, 14–15 centimetres long, with a fairly short tail showing little or no white on the outer feathers. Breeding males have bright chestnut-brown upperparts and head, with a yellow breast and belly streaked on the sides. Non-breeding males are similar but duller, with the chestnut partly hidden by pale feather fringes. The female is mostly dull brown with dark streaks above and mainly pale yellow underparts, with a dull chestnut rump and a buff throat. (Wikipedia, general species account)

It breeds in Siberia, northern Mongolia and northeastern China and is a long-distance migrant, wintering in southern China, Southeast Asia and northeast India. The variable, high-pitched song is given from a perch low in a tree. There are a number of records from Europe, but some of these are considered escapes from captivity rather than genuine vagrants.
