"Bonaparte's Gull," Wikipedia, the free encyclopedia. Bonaparte's gull is a small gull found mainly in North America. Bonaparte's gull is among the smallest of the gull species; only little gull and Saunders's gull are smaller. Adults range from 28 to 38 cm (11 to 15 in) in length, with a wingspan of 7684 cm (3033 in) and a body mass of 180225 g (6.37.9 oz). There is no difference in plumage or bare part color between the sexes, though males tend to be heavier than females. Bonaparte's gull is smaller-bodied, smaller-headed, and smaller-billed than the other common hooded gulls of North America. The adult has grey upperparts and white underparts; its wingtips are black above and pale below. In breeding plumage, it has a slaty black hood, which it loses in non-breeding plumage. Its short, thin bill is black, and its legs are orangish-red.
