Until recently the identification of Canada Goose was extremely easy on the Pribilofs. However, in 2004 the American Ornithologist Union decided to split the smaller tundra breeding subspecies of Canada Geese from the larger more easterly/southerly breeding subspecies. Prior to 2004 records of Canada Goose in the Pribilofs were not generally identified to subspecies. The form of “Canada Goose” that regularly occurs in the Pribilofs is the leucopareia, or “Aleutian Goose” which is now considered to belong to the newly formed species, Cackling Goose (Branta hutchinsii). It is likely that proper Canada Geese, of the subspecies parvipes or possibly even fulva do occasionally occur on Saint Paul. Currently the only confirmed Canada Goose record for the island was furnished by a single bird on Webster Lake in June of 2004.
