Siberian Accentor
Prunella montanella
The Siberian accentor is on average 14.5 centimetres (5.7 in) long and weighs 17.5 grams (0.62 oz). The adult of the nominate race has brown upperparts and wings, with bright chestnut streaking on its back and a greyish-brown rump and tail. There are two narrow whitish bars on the folded wings. The head has a dark brown crown, a long, wide pale yellow supercilium, a blackish patch behind the eye and grey sides to the neck. The underparts are ochre yellow, becoming strongly buff on the flanks and greyish on the lower belly. Voice: The call of the Siberian accentor is a trisyllabic ti-ti-ti. The male's song, given from the top of a bush or tree, is a loud, high chirichiriri, variously described as similar to that of the Japanese accentor, the dunnock or the black-throated accentor. Breeding birds sing most vigorously early in the season, particularly at dawn, and some individuals may also sing on migration.
