Facts about Ross's Gull it is a petite seabird that belongs to the genus Rhodostethia of the family Laridae. The binomial name of Ross's Gull is Rhodostethia Rosea, and it is the only gull in its genus, even though it has been suggested it is supposed to be moved to the Hydrocoloeus genus that otherwise includes the Little Gull only. This marine bird is named after James Clark Ross, the British explorer. The breeding grounds of the Ross's Gull were first discovered during 1905 by a Russian ornithologist, Sergei Aleksandrovich Buturlin, close to the Pokhodsk village in the Northeastern part of Yakutia, a Russian federal subject, while visiting the region as a judge.
The Ross's Gull is a small gull that has a body length, ranging from 11.4 inches to 12.2 inches (29 cm to 31 cm), with a wingspan between 35.4 inches and 39.4 inches (90 cm and 100 cm), and with a body mass that ranges from 140 grams to 250 grams (4.9 Oz to 8.8 Oz).
The Ross's Gull is analogous in size and some plumage attributes to the smallest gull. The Ross's Gull is somewhat longer winged and bigger than that other gulls in its genus and it has a wedge-shaped tail and sharper wings. The legs of the Ross's Gull are red in color. Summer adult Ross's Gulls have pale gray upper parts and white underparts, with a pink color to their breast, and a neat black colored neck ring. During winter, the breast shades and the neck collar are lost and a little dark crescent enlarges at the back of their eyes.
The juvenile birds of the Ross's Gull will look like the winter adults, but these young birds will boast a dark "W" design on their wings during their flight. The young birds of the Ross's Gull variety take two years to attain their complete adult plumage.
Ross's Gulls breed in the elevated Arctic of the northernmost parts of North America, and the northeastern parts of Siberia. The Ross's Gull is a migratory bird, and it migrates only small distances south during autumn. However, the majority of the Ross's Gull will winter in northern latitudes at the border of the pack ice in the northern part of the Bering Sea and in the Okhotsk Sea, whereas some other gulls will reach more temperate regions, like North West Europe. The Ross's Gull can be largely seen as far as south of the Salton Sea in California. Their summer breeding grounds include tundra with grass tussocks, sedges, dwarf willows, lichens, bushes, and pools.
The Ross's Gull mostly feeds on any appropriate small prey, like crustaceans and small fish, and during the winter season it regularly feeds on mudflats, such as a wader. During the breeding period, the Ross's Gull is mostly insectivorous, feeding on flies and beetles.
The Ross's Gull usually breeds in small settlements on tundras and marshy Arctic estuaries, habitually nesting with other marine birds, like Arctic terns. The female Ross's Gull is capable of laying two to three eggs in a single clutch. The Ross's Gull usually lay their eggs in the nest, constructed on the ground, which is lined with grass, seaweed, or moss, habitually on an island in a little pond. Their eggs assume the olive green color with small reddish-brown dots. Eggs are protected for three weeks and the young birds fledge in an additional period of three weeks.
The average lifespan of the Ross's Gull is 21 years.
