Branta bernicla
The Brant Goose, scientifically known as *Branta bernicla*, is a small, compact marine goose, easily distinguished by its black head and neck, offset by a crisp white neck patch that acts as a key identification mark in the field. Its body plumage is a varying shade of dark gray-brown, appearing darker on the back and lighter on the belly, with subtle barring on the flanks. Adults typically measure 55-66 cm (22-26 inches) in length, possess a wingspan of 106-121 cm (42-48 inches), and weigh b...
Primarily found in coastal marine environments, intertidal zones, and estuaries during migration and winter; breeds on Arctic tundra, often near freshwater ponds or rivers.
Primarily herbivorous, feeding almost exclusively on marine vegetation like eelgrass and sea lettuce during winter and migration, supplementing with terrestrial grasses, sedges, and mosses on breeding grounds.
Brant Geese are highly social birds, spending most of their time in large, cohesive flocks, particularly outside the breeding season. They are diurnal, dedicating much of their day to foraging, interspersed with periods of resting, preening, and social interaction. Foraging involves extensive gra...
The Brant Goose is a Holarctic species with a vast breeding range across the Arctic tundra of North America, Europe, and Asia. In North America, the Pacific Brant (*B. b. nigricans*) breeds from northern Alaska eastward through the Canadian Arctic Archipelago, wintering primarily along the Pacifi...
Least Concern
- The Brant is sometimes called the 'sea goose' due to its strong association with coastal marine habitats and its diet of marine vegetation. - Their diet is so specialized that a significant decline in eelgrass beds, often due to disease or human activity, can severely impact Brant populations. ...
