Note: Terns differ from gulls chiefly in their graceful form,
in their weaker and more slender bills and feet, and
their longer and more pointed 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. paradis[ae]a}), the roseate
tern ({S. Dougalli}), the least tern ({S. Antillarum}),
the royal tern ({S. maxima}), and the sooty tern ({S.
fuliginosa}).
