INTERESTING FACTS
- The Gull-billed tern has a number of geographical races, differing mainly in size and minor plumage details.
- They don't normally plunge dive for fish like the other white terns, but feeds on insects taken in flight, and also often hunt over wet fields, to take frogs and small mammals.
- They are less numerous today on the Atlantic coast than at their historical levels, prior to the millinery trade in the late 1800s.
A group of terns are collectively known as a "ternery" or a "U" of terns.
