Siberian Blue Robin

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 Neo-Latin larva meaning caterpillar and -vorus meaning eating, and cyane is Latin for "dark-blue".
