Songbird species (Emberiza citrinella, family Emberizidae) found from Britain to central Asia. The name is derived from the German Ammer (bunting). Yellowhammers are 6 in. (16 cm) long and have a streaked brown body, yellow-tinged head and breast, and a rapid song. In the southern U.S., the yellow-shafted flicker is called yellowhammer because of its drumming.
