Distribution

The North American midcontinent birds of the subspecies A. a. gambeli—which in 2010 had a fall population of about 710,000 birds—breeds from the Alaska North Slope across the western and central Canadian Arctic.The Pacific white-fronted goose of the American Pacific coast, which in 2010 numbered approximately 650,000 birds,[citation needed] and the tule geese, which are estimated to number 10,000 birds, nest in western Alaska. The midcontinent geese gather in early fall on the prairies of western Saskatchewan and eastern Alberta, spending several weeks feeding before heading to wintering areas near the Gulf of Mexico, into northern Mexico. The Pacific birds migrate south down the Pacific coast, staging primarily in the Klamath Basin of southern Oregon and northern California and wintering, eventually, in California's Central Valley. The tule goose is somewhat rare and has been since the latter half of the 19th century,presumably it was affected by destruction of its wintering habitat due to human settlement.

In the British Isles, two races overwinter: Greenland birds in Scotland and Ireland, and Russian birds in England and Wales. They gather on farmland at favoured traditional sites, with a famous flock gathering at WWT Slimbridge, Gloucestershire, England. Greenland birds also overwinter in Ireland and from late September and through the winter months, Ireland is home to almost 50% of the Greenland population of white-fronted geese.

A. a. albifrons and A. a. flavirostis are among the taxa to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
