Yellowhammer

The yellowhammer is a bunting native to Eurasia and introduced to New Zealand and Australia. The male has a bright yellow head, streaked brown back, chestnut rump and yellow underparts. Most European birds stay in the breeding range year-round, but the eastern subspecies is partially migratory, and it has occurred as a winter vagrant in the Himalayas from northern Afghanistan to central Nepal. The source does not describe its status in China. (Wikipedia, general species account)

Its song has a rhythm like 'A little bit of bread and no cheese' and is very similar to that of its closest relative, the pine bunting, with which it interbreeds. Breeding begins mainly in April and May, with the female building a lined cup nest. The three to five eggs are marked with fine dark lines, giving the old name 'scribble lark', and the female incubates for 12–14 days. (Wikipedia, general species account)
