Sushkin's goose
Species of goose thought to be extinct
Sushkin's goose (Anser neglectus) is a putative species of goose now thought to be extinct. The status as a species has remained contested. It has sometimes been considered a subspecies of the bean goose but some have proposed, based on descriptions in life and specimens, that it was distinctive enough to be treated as a full species. It has been suggested that the Tunguska event of 1908 may have wiped out most of the breeding population in the Taiga region resulting in its dwindling to extinction. Some geese with "neglectus" type characters have been recorded suggesting that the last few populations hybridized with other geese such as the tundra and taiga bean goose in the breeding region.
