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 ({
Sterna paradisaea }),
the roseate tern ({
Sterna Dougalli }),
the least tern ({
Sterna Antillarum }),
the royal tern ({
Sterna maxima }),
and the sooty tern ({
Sterna fuliginosa }).
