Arctic Tern Behavior

The Arctic Tern is a graceful flier that hovers over its feeding grounds and nest colonies. They hunt on small fish swimming close to the water surface diving into a 20-inch dive and comes out swallowing the fish head first. Males fly lower over their colonies with their bills filled with fish in order to capture the attention of a female. Females who are interested in turn fly after the male flying over him with her straight body. The courtship continues as the male offers food to the female, feeding her as they bond.

Arctic Tern Diet

The Arctic Terns are carnivores and their diet includes fish, crustaceans, and insects. The diet varies with season and location, the diet mostly includes small fish, crustaceans, and insects in summer on breeding grounds. They are also known to eat mollusks, marine worms, earthworms and sometimes they are known to eat berries. Then they plunge into the water to scoop up the prey, which they can even eat while gliding.

Arctic Terns feed mostly on small fish and occasionally insects from the air or water surface. During their extensive migration, they forage with other seabirds following predator schools of fish that force the smaller fish to swim close to the water surface.

Arctic Tern Habitat

Arctic Terns breed across the Arctic in treeless areas with little to no vegetation, in open boreal forests, and on islands and barrier beaches on the northeastern Atlantic Coast. They migrate over the Atlantic and Pacific Oceans to food-rich waters around Antarctica where they hang out on pack ice during the Southern Hemisphere’s summer.

Their breeding grounds are mostly treeless with no ground cover or beaches along the north Atlantic Coast. Their migration is usually offshore but some travel overland.

Nesting

They first breed at the age of 3-4 years. They nest in colonies, sometimes with other terns. Much of courtship between the sexes are aerial, with groups and pairs performing high flights. The male may fly over the colony carrying fish, wings beating high above back. On the ground, a pair of birds posture, bow, strut in circles. Male presents fish to female. The nest site is on the ground in the open. The nest is built by both sexes and is a shallow scrape, usually lined with a few bits of plant material, debris. The young leave the nest 1-3 days after hatching and find a place to hide nearby. Both parents bring food to the young.  The young hatchling takes its first flight 21-28 days. The young remain with parents another 1-2 months.

Range and Migration

Arctic Terns migrate from pole to pole, birds in North America travel around 25,000 miles each year. They fly at about 35 to 40 kph. It spends much of its time resting on small blocks of ice. it flies from its Arctic breeding grounds to the Antarctic and back again each year. The long journey ensures that this bird sees two summers per year and more daylight than any other creature. They start leaving the wintering grounds in March and reach coastal North America during late April with greater numbers passing through in May. Breeds on coasts and tundra from New England, Washington, and Britain north to the northernmost limits of the land, and spends the rest of the year at sea.

Arctic Tern Lifecycle

The nesting site is usually on the ground surface near water sources. Males and females scrap on the ground of an existing hole or ground on the surface. Female Arctic Terns lay 1 to 3 eggs and incubates them for 23 days. 28 days after hatching the chicks are strong enough to leave the nest.
