Arctic & Common Terns Nesting - English
URL: http://www.birdingamerica.com/Maine/terns.htm

Arctic terns are fascinating birds. They are the longest of long-range migrants, moving annually between breeding grounds in the Arctic and sub-arctic and wintering grounds south to the Antarctic ice-pack. It's tough to imagine such a journey undertaken each year, especially for a species such as ours, that routinely complains of the discomforts of air travel at much shorter distances.

Terns of Florida - English
URL: http://edis.ifas.ufl.edu/UW100

Terns are enjoyed by millions of people who flock to Florida's beaches. Although only adorned with various shades of black and white feathers, terns are beautiful birds. They are in the same taxonomic family, Laridae, as gulls. This means they share some common physical and behavioral characteristics. For example, gulls and terns have webbed feet and usually nest on the ground and near water. Terns differ from gulls in that they have narrower pointed wings, forked tails, pointed bills, and slimmer bodies. Their bill is often aimed downward as they fly and hover in search for food. Of the 16 species of terns in North America, 12 can be seen in Florida.
