Showing primary migration corridor(s) for this species
Baer's pochard (Aythya baeri) is a diving duck found in eastern Asia. It is a resident bird in North and Central China, and formerly bred in southeast Russia and Northeast China, migrating in winter to southern China, Vietnam, Japan, and India. Baer's pochard is a monotypic species. The holotype was collected in middle Amur. It has a distinctive black head and neck with green gloss. While in poor light, it is likely to look completely black. It is similar and closely related to the ferruginous duck, and they were previously considered to be a single species; Baer's pochard is differentiated by its white flanks when floating on the water, as well as its longer, more rounded head and larger size. Its breeding season varies by latitude and environment.
