Brant
A small sea goose that depends on eelgrass for its survival and almost disappeared when eelgrass died off many years ago. Both are plentiful now.

Common Tern
White bird with black cap that dives from the air to catch fish. It has the longest migration route of any bird—almost pole to pole!

Great Black-backed Gull
Largest gull in the world with a 5–6 foot wingspan. It lives on Cape Cod year-round.

Herring Gull
A large gray and white gull with a yellow bill that lives on Cape Cod year-round. These gulls will eat almost anything.

Laughing Gull
A smaller, black-headed gull that comes here to nest and is named for its “ha-ha” call.

Northern Gannet
A very large pelagic seabird with long pointed wings that plunge dives for fish from high in the sky. Adults have white wings with black tips. Gannets rarely come on shore because they can’t take off from land.
