Подробности наблюдения
With Snow Geese. In photo below, it is at bottom center. The dark head with dark neck is a feature of Greater White-fronted Goose. However, this feature is shared with juvenile of Snow and Ross's Goose. So note lack of black primaries and presence of black tail, which definitely separates Greater White-fronted Goose from these two other species at whatever age. White undertail coverts and vent provide confirming marks.
