Emberiza cirlus
Slightly more compact than Yellowhammer, with shorter wings and heavier bill. In all plumages note; olive to grey rump, greyish lesser coverts and finely streaked flanks. Male unmistakable with black throat and eye-stripe. Female and immature lacks black throat, but have more contrasting eye- and moustache-stripe than Yellowhammer.
Song variable, but can generally be described as a Yellowhammer phrase with no ending, or an Arctic Warbler with bunting timbre. Tempo also variable, but rhythm always even. Alarm call a thin "tseeep", similar to Rock Bunting, but more drawn out.
