Greetings All,
I may have sowed the seeds of confusion Black Brant: breed w. Canada to eastern or central Siberia. Winter mostly along Pacific, in North America, from BC south to Baja California Sur. Vagrant have shown up all across the n. Hemsiphere Black-bellied Brent Goose. Breeds Siberia. Winters Europe. Vagrant to North American Atlantic Coast. Apparent hybrids with Black Brant have appeared in Pacific NW. Individuals of this population have been found migrating between Ireland and Canada but never actually on the eastern Canadian breeding grounds. Gray-bellied Brant. Breeds Western High Arctic in Canada. Winters primarily in Puget Sound area. Vagrants, apparently of this taxa have appeared in Europe, California, perhaps elsewhere Eastern High Arctic Brant. Breed in Eastern High Arctic of Canada. Winter primarily in Ireland/British isles. Vagrants around Europe, probable farther east. Since lumped with Eastern Low Arctic birds, and look very similar, who knows where they've wandered to. Eastern Low Arctic Brant. Breeds farther s. in eastern Canada. Winters on North American Atlantic coast. Hard to know if interior "Atlantic Brant" pertain to low or high arctic birds, or both. Finally, Gray-bellied Brant can be as pale as any Atlantic Brant, so birds that appear to be Atlantic Brant that have appeared on Pacific Coast are assumed to be from the GB Brant population, but ???
