Ross's Goose Anser rossii

Sign in to see your badges



Cute miniature version of Snow Goose with smaller body, shorter neck, and stubbier bill. Pay special attention to the bill: short, with a straighter border where it meets the face, a much less obvious dark “grin patch,” and often bluish-gray color at the base. Also note clean white head; Snow Goose typically has yellowish staining on face. Hybrids with Snow Goose are rare but regular; some intermediates might be best left unidentified. Dark morph Ross’s is extremely rare. Typically found in flocks, but individuals may be found with other geese species. Frequently in large mixed flocks with Snow Geese. Occurs in fields, marshes, and lakes during migration and winter; breeds on Arctic tundra.
