Charadriiformes is a diverse order of small to medium-large Birds It includes about 350 Species and has members in all parts of the world Gulls (often informally Seagulls) are birds in the family Laridae Larus is a large genus of Gulls with worldwide distribution (although by far the greatest Species diversity in the Northern Hemisphere) pacificus

Binomial name

Larus pacificus
Latham, 1802

The Pacific Gull (Larus pacificus) is a very large gull, native to the coasts of Australia. John Latham ( June 27, 1740 - February 4, 1837) was an English Physician, naturalist and Author. Gulls (often informally Seagulls) are birds in the family Laridae For a topic outline on this subject see List of basic Australia topics. It is moderately common between Carnarvon in the west, and Sydney in the east, although it has become scarce in some parts of the south-east, as a result of competition from the Kelp Gull, which has "self-introduced" since the 1940s. Carnarvon is a coastal town situated approximately 900 kilometres north of Perth, Western Australia.

Much larger than the ubiquitous Silver Gull, and nowhere near as common, Pacific Gulls are usually seen alone or in pairs, loafing around the shoreline, steadily patrolling high above the edge of the water, or (sometimes) zooming high on the breeze to drop a shellfish or sea urchin onto rocks. The Silver Gull ( Chroicocephalus novaehollandiae) also known simply as "seagull" in Australia is the most common Gull seen in Australia Shellfish is a Culinary and Fisheries term for those aquatic Invertebrate animals that are used as Food: various species of molluscs Sea urchins are small globular spiny sea cat animals composing most of class Echinoidea.

Description

Adult Pacific Gulls range from 58 to 66 cm in length, and are white, with dark wings and back, and a 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. In Zoology, as in other branches of Biology, subspecies is the Taxonomic rank immediately subordinate to a Species. 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.
