This subspecies is not well known, moreover it is not accepted by several ornithologists and treated as identical with the Aleutian Cackling Goose (Branta hutchinsii leucopareia (Brandt)).

The Gackling Geese from the Komandorski- and Kuril Islands (if distinct or not) went extinct after the introduction of Arctic Foxes (Alopex logopus (L.)) by Russian fur traders.

The last sighting dates from the 07.02.1926, when a bird was observed in the Japanese winter refuge.
