Genus Xema
Sabine's gull (/ˈseɪbaɪn/ SAY-bine or /ˈsæbaɪn/ SAB-ine) (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.[2] 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.
