A small, delicate gull with a small head and a slender, straight bill. It has long, pointed wings and a forked tail.
Relative Size
Larger than a Common Tern, smaller than a Ring-billed Gull.
crow-sizedStriking black-headed gull on the breeding grounds in the Arctic. Bill is black with a yellow tip.
Juveniles have a brownish back that appears scaly and a brownish neck. The outer primaries are black, narrowly edged in white.
Sabine's Gulls typically nest along pond edges, on islands, or on low-lying marshy tundra near the shore.
Nonbreeding birds have black primaries, white secondaries, and a gray back. A smudgy gray partial hood marks the head. The tail is entirely white.
Breeding birds in flight have black primaries, white secondaries, and a gray back, all of which form triangular patches of color.
Juveniles in flight look similar to breeding adults, but have paler triangular blocks of color and the tail is tipped in black.

Larger than a Common Tern, smaller than a Ring-billed Gull.
crow-sizedBreeding adults are white with a dark head (gray bordered in black) and a three-toned wing pattern. In flight, the upperwings are gray with a black triangle in the outer primaries and a white triangle along the trailing edge. Up close, breeding adults show a red eyering and a black bill with yellow tip. Nonbreeding adults have white speckles on the head and a dusky eyering. Juveniles are brown above, not gray, with pale feather edges that impart a scaly appearance; they have an all-black bill and a black tip to the tail.
Often forages on the wing, over ocean and large rivers or lakes, with agile dips down to seize prey near the surface. In and around tundra ponds, Sabine's Gulls walk, wade, or swim to catch insects and larvae with the bill, sometimes using the feet to stir up prey. On mudflats, races around like a plover to capture worms or small crustaceans. Migrates and forages at sea in flocks.
Nests on arctic and subarctic tundra in marshy areas, often with extensive mixtures of marshes, ponds, and lakes. Winters in the open ocean near areas of upwelling. Migrants sometimes appear far inland, where they usually seek rivers and lakes.
