Siberian blue robin

Larvivora cyane

The Siberian blue robin is a small passerine bird that was formerly classified as a member of the thrush family, ''Turdidae'', but is now more generally considered to belong to the Old World flycatcher family, ''Muscicapidae''. It and similar small European species are often called chats. Recent research suggests that this species and some other East Asian members of ''Luscinia'' should be classified in a new genus, together with the Japanese and Ryūkyū robins. The genus name ''Larvivora'' comes from the new Latin ''larva'' meaning caterpillar and ''-vorus'' meaning eating , and ''cyane'' is Latin for "dark-blue".

This bird is a migratory insectivorous species breeding in eastern Asia across to Japan. It winters in southeast Asia and Indonesia.

The breeding habitat is coniferous forest with dense undergrowth, often beside rivers or at woodland edges. It feeds on the ground but is very 'skulking'. In winter, this bird also tends to stay in dense vegetation.

This species is larger than the European robin. The breeding male is unmistakable with blue upperparts and white underparts. The female is much drabber, with brown upperparts and whitish underparts. Her dark eye stands out against the paler brown face.

This species is a very rare vagrant to Europe, and has vagrant status even as far east as Pakistan.

The Siberian blue robin was previously placed in the genus ''Luscinia''. A large molecular phylogenetic study published in 2010 found that ''Luscinia'' was not monophyletic. The genus was therefore split and several species including the Siberian blue robin were moved to the reinstated genus ''Larvivora''.
