Siberian Blue Robin Larvivora cyane

A slender, long-legged songbird with a “crouched” profile. Adult male is unmistakable, with blue upperparts and snow-white belly separated by black running from the eye to the bend of the wing. Female warm brown with blue-tinted rump and whitish underparts. Juvenile resembles female but grayer above. Like most other robins, shy and retiring, inhabiting forested areas with dense undergrowth; on its breeding grounds, most easily detected by its song, an explosive “tsi-tsi-TEWEE-TEWEE.”
