Look for them on coastal mudflats at low tide in winter. They look almost black from a distance when sitting on the water.

✦ Fun Fact

In the 1930s, a blight struck eelgrass, and the Brant Goose population crashed. They have since adapted to graze on agricultural fields near the coast.

About

A small, dark goose, only slightly larger than a Mallard. It is a coastal bird that breeds in the Arctic tundra. Brant Goose spends winters on coastal waters and salt marshes of Western Europe. It has a black head and neck with a small white 'necklace' on the side. The 'dark-bellied' variety is the most common in Europe.

Behaviour

Brant Geese stay near the coast outside the breeding season. They eat eelgrass, sea lettuce, and salt-marsh grasses. They move in large, low-flying flocks. These flocks lack the disciplined V-formation of larger geese. Their call is a soft, guttural 'rronk-rronk'.
