Baikal Teal
Sibirionetta formosa
The Baikal teal (Sibirionetta formosa), also called the bimaculate duck or squawk duck, is a dabbling duck that breeds in eastern Russia and winters in East Asia.
At between 39 and 43 centimetres, this duck is slightly larger and longer-tailed than the common teal. The breeding male is unmistakable, with a striking green nape, yellow and black auriculars, neck, and throat. It has a dark crown, and its breast is light brown with dark spots. It has long dropping dark scapulars, and its grey sides are set off on the front and rear with white bars.
