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 (1.98 to 2.60 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. They have salt glands that secrete salty water through the nostrils. 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. Of the two subspecies, the nominate eastern race prefers sheltered beaches, and the western race L. p. 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.

Feeding Habits
Pacific Gull's diet includes fish, molluscs, squid, crabs, sea-urchins, crustaceans, small seabirds, eggs, and nestlings. They forage by scavenging carrion or hunting live prey and show a preference for diverse marine-based food sources.
Habitat
Pacific Gull primarily inhabits coastal environments, including beaches, estuaries, sheltered bays, and harbours. It has a preference for sandy shores, occasionally favoring rocky coasts, particularly in eastern regions where it seeks protection from ocean swells. Although mainly a coastal bird, pacific Gull is sometimes found inland on farmlands and rubbish dumps near the shore and may venture up rivers. Habitually, it avoids dense human populations but is known to roost on elevated structures like rocky headlands, or man-made wharves and jetties. Its breeding grounds are often offshore islands or, less commonly, coastal headlands.
