Common Tern
Terns are smaller and more graceful in flight than gulls. The Common Tern Sterna hirundo (right) grows to 14", wingspan 31". Their forked tails make it easy to differentiate terns from Laughing Gulls, which also have black heads.
Terns are found in the same habitats as gulls, that is to say, just about anywhere near water. Their call is a common sound along waterfronts everywhere.
