Key Field Marks

  • Size & shape: A small goose, about 60 cm, noticeably smaller and more compact than a Canada Goose, with a short neck and stubby bill.
  • Plumage: Black head, neck, and breast with a small white necklace patch on the sides of the neck (broken or partial); body plumage ranges from pale gray-brown (Atlantic populations) to sooty blackish-brown (Pacific/Black Brant) depending on subspecies.
  • In flight: Shows a dark body with a white U-shaped rump/undertail patch, and flocks often fly in loose, irregular lines rather than tight V formations.

Separating from Similar Species

  • Canada Goose: Much larger, with a bold white chinstrap across the cheeks (Brant lacks any white on the face), and a longer neck; Brant's neck and head are uniformly black with only the small neck-side necklace.
  • Atlantic vs. Pacific (Black) Brant: Atlantic Brant shows a pale, whitish-gray belly contrasting with the dark breast; Pacific/Black Brant has a uniformly dark, sooty belly matching the breast, with a more complete white neck ring.
  • No other regularly occurring goose combines small size, all-dark head/neck, and a partial white neck collar.

Habitat, Range & Season

  • Highly tied to coastal saltwater habitats — bays, estuaries, and lagoons with eelgrass and sea lettuce beds, its primary winter food.
  • Breeds in the high Arctic tundra of North America and Siberia during summer.
  • Winters along both the Atlantic and Pacific coasts of North America (and parts of Eurasia), typically arriving in large numbers in late fall and departing by spring.

Voice

  • A distinctive, guttural, rolling "cronk" or "rrrk-rrrk," quite different from the higher honking of Canada Goose.
  • Flocks feeding or resting on the water give a continuous low, murmuring chorus of these guttural notes.
