Bering Cackling Goose (Branta hutchinsii ssp. asiatica)
The Bering Cackling Goose was described in 1946; it is thought to have been breeding on the Komandorski- and the Kuril Islands offshore the Kamchatka Peninsula in the Bering Sea.
This form disappeared sometimes during the 1920s, probably due to overhunting.

The Bering Cackling Goose is often treated as being identical with the Aleutian Cackling Goose (Branta hutchinsii ssp. leucopareia (Delacour)) (see photo below).
