INTERESTING FACTS
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. The only member of its genus, the Sabine's Gull is like no other gull. Many of its behaviors resemble those of terns more than gulls. This bird was named after the English scientist Sir Edward Sabine by his brother Joseph Sabine.
