Small, light and fast the Arctic Tern can fly 6,000 miles without stopping! The Arctic Tern is monogamous, and the longest flyer on earth. Each year it migrates over 60,000 km (37,000 miles).

They also sleep while they are still aloft. Thus, they fly through the nighttime, forever looking for the lands of the 24-hour sun.

During their migration, arctic terns can be found in the Arctic and Antarctica. Their routes take them north from May to June, and south from November to February.

A loud, and screeching bird—heaven help any other seabird—rat, polar bear, minx, or fox—who want to make off with their chicks. They are aggressive and peck at and dive-bomb any intruders, (including humans).

Mating for life, arctic terns have a courtship ritual. The male bird offers the female a fish.

These terns are also acrobatic. While hovering they can catch insects on the wing. They also eat mollusks, crustaceans, sandeel, krill, crabs, worms, capelan, cod, and herring.

Climate change is expected to take a toll on arctic tern populations, and might affect up to 50 percent of their habitat.

Rising temperatures, habitat loss, and melting ice also can mean a big part of their diet is in decline. Sandeel, or eel-like fish loss can mean arctic terns can no longer feed their chicks, and end up abandoning them. That, or the birds do not mate for the season.
