Little tern 白额燕鸥
The little tern (Sternula albifrons or Sterna albifrons) is a seabird of the tern family, Sternidae. It was formerly placed into the genus Sterna, which now is restricted to the large white terns. The former North American (S. a. antillarum) and Red Sea S. a. saundersi subspecies are now considered to be separate species, the least tern (Sternula antillarum) and Saunders's tern (Sternula saundersi).
