Gull

Gull

In Canada, most seagulls are Herring Gulls Larus argentatus. The adult Herring Gull is about 61 cm long from the tip of its bill to the tip of its tail. Its head, body, and tail are white, its bill is yellow with a red spot on the lower tip, and its legs are pink or flesh-coloured. The backs and upper wing surfaces of adult gulls are grey, and the tips of their outermost flight feathers are black with a white spot. In winter, the heads of adult gulls are streaked with brown. Immature birds are a mottled brown and take four years to develop full adult plumage.
