NL. sterna.] (Zoöl.) Any one of numerous species of long-winged aquatic
birds, allied to the gulls, and belonging to Sterna and various allied

wings. The tail is usually forked. Most of the species are white with
the back and wings pale gray, and often with a dark head. The common
European tern (Sterna hirundo) is found also in Asia and America. Among
other American species are the arctic tern (S. paradisæa), the roseate
tern (S. Dougalli), the least tern (S. Antillarum), the royal tern (S.
maxima), and the sooty tern (S. fuliginosa).
