Sabine's gull ( SAY-bin; Xema sabini) is a small gull. It is usually treated as the only species placed in the genus Xema, though some authors include it with other gulls in a wide view of the genus Larus. It has also been known historically as fork-tailed gull or xeme (from the genus name). It breeds in colonies on Arctic coasts and tundra, laying two or three spotted olive-brown eggs in a ground nest lined with grass. Sabine's gull is pelagic outside the breeding season. It takes a wide variety of mainly animal food, and will eat any suitable small prey.
Sabine's gull was formally described in 1819 by the naturalist Joseph Sabine under the binomial name Larus sabini. Sabine based his description on specimens that had been collected by his brother Captain Edward Sabine, who had accompanied Captain John Ross on a voyage to look for the Northwest Passage. The birds were found breeding on low-lying islands off the west coast of Greenland in July 1818. Sabine's gull is now the only species placed in the genus Xema; the genus was described in 1819 by the zoologist William Leach in an appendix to Ross's account of the voyage. The genus name Xema appears to be an invented name... Wikipedia →

Rare
Under 5% of wildlife watchers report a Sabine's Gull sighting in Death Valley National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 193rd most-seen of the 213 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
September and October
In those months about 10% of wildlife watchers report a Sabine's Gull in Death Valley National Park on a given day, against under 5% in November to August, the lowest months. Those are among Death Valley National Park's driest months, with about 10 mm of rain a month against 30 mm in March.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Sabine's Gull sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 14
Of the 14 parks where we can rate Sabine's Gull sightings, Death Valley National Park ranks 6th at under 5%. The best odds are in Kenai Fjords National Park (United States, about 10%), Svalbard (Norway, under 5%) and Nahuel Huapi National Park (Argentina, under 5%).
GBIF citizen-science records
It is estimated from how often the Sabine's Gull is recorded against all the birds logged in Death Valley National Park (7 verified sightings from 2019 to 2026), 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.
