Sabine's Gull
 The Sabine's Gull (Xema sabini) also known as the Fork-tailed gull or Xeme is a small gull. Its generic placement is disputed; some authors treat it as the sole species in the genus Xema as Xema sabini while others retain it in the genus Larus as Larus sabini. It breeds in the Arctic and has a circumpolar distribution through northernmost North America and Eurasia.
