Fieldmarks: Mid-sized gull with
head-to-tail length of 45-53 cm (18-21 in). Like most gulls, age and
seasonal plumages are variable. Most individuals in this region are
sub-adults. Legs are flesh-colored. Heavy 'ringed' bill separates this
species from other common Western North Atlantic gulls of similar size. Occurrence: Can occur at any season, but mostly December
through March. Fairly common in the Gulf of Mexico, Bermuda, northern
Bahamas, Cuba, and Cayman Islands. Rare elsewhere in the Antilles and
quite rare in the Lesser Antilles. Rarely, vargrants are reported from
Trinidad, Venezuela, and Panama. This species is increasing in numbers
and its winter range is expanding.
Breeds in North America on inland lakes and praries of central US and
Southern Canada. Infrequently seen at sea. Typically found in fields,
parking lots, freshwater ponds, and coastal habitats. Requires 3 years
to attain adult plumage.
