Description
Pacific Gulls are the only large gulls in their range, besides the occasional Kelp Gull. This species can range in length from 58 to 66 cm (23 to 26 in) and span 137 to 157 cm (54 to 62 in) across the wings. They typically weigh from 900 to 1,180 g (2.0 to 2.6 lb). This species is mostly white, with dark wings and back, and a very thick (when compared to other gull species), powerful, red-tipped yellow bill. Young birds are mottled-brown all over, and attain their adult plumage only gradually: by its fourth year, a young Pacific Gull has usually become difficult to tell apart from an adult bird.
There are two subspecies: the nominate eastern race prefers sheltered beaches, the western race georgii is commonly found even on exposed shores. Both subspecies nest in pairs or loose colonies on offshore islands, making a cup of grasses and sticks in an exposed position, and laying two or three mottled brown eggs.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
