The Greater White-fronted Goose has a distinctive white patch at the base of its bill and orange legs, while the Brent Goose lacks the white facial patch and has black legs. Both species are migratory, but they prefer different habitats during breeding and wintering.

Look for the white patch at the base of the bill and orange legs to identify the Greater White-fronted Goose. In contrast, the Brent Goose will have black legs and no white facial patch.
