Rhodostethia rosea (Ross's Gull)

Synonyms: Hydrocoloeus roseus; Larus roseum; Larus rossii

Wikipedia Abstract

The Ross's gull (Rhodostethia rosea) is a small gull, the only species in its genus, although it has been suggested it should be moved to the genus Hydrocoloeus, which otherwise only includes the little gull.This bird is named after the British explorer James Clark Ross. Its breeding grounds were first discovered in 1905 by Sergei Aleksandrovich Buturlin near village of Pokhodsk in North-Eastern Yakutia, while visiting the area as a judge. The genus name Rhodostethia is from Ancient Greek rhodon, "rose", and stethos, "breast". The specific rosea is Latin for "rose-coloured".
