Gull
Adult gulls are mainly gray or white, with variable head markings. In
breeding season the head is either pure white, black, gray, or brown; it
becomes streaked or smudgy in winter. The bill is strong and slightly
hooked and in some species shows a spot of colour. Bill and leg colours
help to distinguish species, as do wing patternSeveral genera are usually recognized for certain specialized gulls, but many authorities place these in the broad genus Larus.
Conspicuous and gregarious, gulls are most abundant as breeders in the
Northern Hemisphere, which has about 30 species in temperate to Arctic
regions. They are mostly colonial ground nesters, and those that breed
inland usually go to coasts in winter.
