Discussion
Bulky goose. Adult has diagnostic white "blaze" on forehead. Several subspecies are recognized, but plumage variability often makes precise identification difficult. Broadly speaking, there are two extremes: pale tundra-breeding forms and darker taiga-breeding birds; they usually occur in separate populations in winter. So-called "Tule Goose" is a particularly dark taiga form. Sexes are similar. All White-fronts fly in V-formation on migration and in winter. Feed by grazing vegetation, particularly grasses in winter.
