  2. low-lying areas of grasses and sedges with small pools; and
  3. some shallow lakes.

Breeding Evidence Map

Rossís Gulls breed in widely varying Arctic habitats, from marshy tundra to gravel reefs. All sites are located near water and many are close to colonies of Arctic terns.

They are extremely rare breeders and found in Manitoba only near Churchill.
