White-billed Diver

Gavia adamsii (G.R. Gray, 1859)

Name in other languages

The White-billed Diver is a rare, locally distributed species of arctic shores and Holarctic tundras. It breeds only locally in Taymyr, namely in the typical tundra subzone and further south; in western Taymyr it breeds up to the northern taiga boundary (Vronsky 1986; Krechmar 1966). There is very little exact information on the species' breeding records in Taymyr (Krechmar 1966) making it difficult to determine more precise relationships between the species and the zones. Typically, it breeds on flat or hilly tundra near large lakes richly supplied with fish. The species is rare everywhere; the total number of birds in the breeding population is also low because of its local distribution, and the species is included in the RF Red Data Book.
