Some 50-60 Canada Geese (Branta canadensis) inhabit Kaliktagik Island, Alaska, in summer (late April to mid-September); in 1980 the corresponding population size was 80-90 adults and young on the wintering area in Oregon. The birds are morphologically intermediate between subspecies leucopareia and taverneri. They are ecologically distinctive for their use of a nesting environment which is unlike that used by any other Canada Geese escept those on Buldir Island, 1800 km west. These facts, together with historical records, suggest this population is a remnant one, possibly representing the eastern margin of a former continuum of island populations extending from the western Gulf of Alaska to the Commander and Kurile Islands of the Soviet Union.
