Regional Differences

In eastern North America, the Atlantic Brant has a mottled brown-and-white belly (subspecies hrota; known in the United Kingdom as Light-bellied Brent Goose). In the West, the much darker Black Brant (subspecies nigricans) is common. Birders around Puget Sound may also see a gray-bellied form, often called Gray-bellied Brant, which breeds only in the Parry Islands of northwestern Canada. Other subspecies occur in the species Old World range.
