Abstract  The Relict Gull (Larus relictus) is recognized as a vulnerable species, with a worldwide population of about 6,000 individuals. Always inhabiting the extreme arid regions of Central Asia, their migratory routes and winter grounds are unclear. This research focused on distribution sites, habitat, behavior, population size and seasonal changes of Relict Gull. Line transects and point counts in every month were used to investigate the gulls around the Ebinur Lake. The result showed Relict Gull was summer visitor to Xinjiang, Western China. Population curve with a single peak was obtained. This gull appeared in early April and was 63 individuals (1% of the global population). The number remained stable from May to July in 2009. The discovery of fledglings indicates that Relict Gull may breed here. They left Ebinur Lake in August. Relict Gull in Ebinur Lake should belong to the Central Asian subpopulation, which was the most westerly record in China.
