Cirl Bunting
Emberiza cirlus
The cirl bunting is like a small yellowhammer (Emberiza citrinella), and is around 15.5 cm (6.1 in) in length with a wing-span 22–25.5 cm (8.7–10.0 in). It has a thick seed-eater's bill. The male has a bright yellow head, with a black crown, eyestripe and throat, and a greenish breast band across its otherwise yellow underparts, and a heavily streaked brown back. The female is much more like the yellowhammer, but has a streaked grey-brown rump and chestnut shoulders. The monotonous song of the male is a rattling trill, like the Arctic warbler or the terminal rattle of the lesser whitethroat.

Ortolan Bunting
Emberiza hortulana
The ortolan bunting is 16–17 centimetres (6+1⁄4–6+3⁄4 inches) in length and has a wing-span of 23–29 cm (9–11+1⁄2 in). In appearance and habits it much resembles its relative the yellowhammer, but lacks the bright colouring of that species; the ortolan's head, for instance, is greenish-grey, instead of a bright yellow. The song of the male ortolan resembles that of the yellowhammer.
