The little gull (Hydrocoloeus minutus) is a species of gull belonging to the family Laridae which is mainly found in the Palearctic with some small colonies in North America. It breeds on freshwater lakes and marshes, and spends winters at sea. It is the smallest species of gull in the world, and the only species in the monospecific genus Hydrocoloeus.
The little gull was first formally described as Larus minutus in 1776 by the German ornithologist Peter Simon Pallas with its type locality given as Berezovo, Tobolsk in Siberia. In 1829, Johann Jakob Kaup proposed the genus Hydrocoloeus for this species, and George Robert Gray later formally designated Larus minutus as the type species of the genus. Kaup had also included Larus plumbiceps Meyer, 1822 in his genus Hydrocoloeus; this is a synonym of Chroicocephalus cirrocephalus (grey-headed gull). Hydrocoloeus minutus is the binomial accepted for this species and it is classified in the family Laridae, the gulls and terns, in the order Charadriiformes.
Within the Laridae, its closest relative is Ross's gull Rhodostethia rosea; some authors have even included Ross's gull in Hydrocoloeus rather than giving it its own genus... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Little Gull is recorded against all the birds logged in Saint Petersburg (45 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
