Sterna

Sterna is a genus of terns in the bird family Laridae. The genus used to encompass most "white" terns indiscriminately, but mtDNA sequence comparisons have recently determined that this arrangement is paraphyletic. It is now restricted to the typical medium-sized white terns occurring near-globally in coastal regions.
