Species: L. pacificus
Adult Pacific Gulls range from 58 to 66 cm (23 to 26 in) in length, and are 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.
The Pacific Gull (Larus pacificus) is a very large gull, native to the coasts of Australia. It is moderately common between Carnarvon in the west, and Sydney in the east.
