The Brent Goose (Branta bernicla) is a small, dark goose known for its striking black head, neck, and chest, with a white patch on the neck and lighter underparts. These migratory birds breed in the high Arctic tundra and winter along temperate coastlines, often seen in coastal marshes and estuaries. Brent Geese are primarily herbivores, feeding on seagrass, eelgrass, and coastal vegetation. Their long migrations between the Arctic and temperate regions showcase their endurance and adaptability. Studying Brent Geese populations helps researchers understand migratory patterns and the effects of climate change on Arctic breeding grounds and coastal ecosystems.
