What does a Arctic Tern do in winter?
During winter, it is almost entirely dark. The arctic tern, going from Arctic summer to Antarctic summer, may experience more daylight than any other animal. Terns migrate in search of summer sunlight. Sunlight illuminates the ground and the ocean surface, so the birds can see fish or insects more clearly.
What do arctic terns do as the Arctic winter begins?
When molting its wing feathers during the winter, the Arctic Tern rarely flies; instead it spends much of its time resting on small blocks of ice at the edge of the pack ice.
How does an Arctic Tern adapt to changing seasons?
There are several adaptations that help Arctic terns survive in their habitat. They are excellent fliers and are able to fly long distances every year between the Arctic and the Antarctic. The Arctic tern has a small body with long pointed wings and a long pointed tail. Hollow bones makes the bird’s body light.
What is the winter ground for Arctic Tern?
Their winter habitat extends to the northernmost points of Antarctica. Breeding grounds range in type and include boreal forests, islands, tundras, and rocky beaches. After migration, the birds spend their winter on pack ice. During this time, they undergo a molt and lose most of their feathers.
Where does the Arctic tern spend the summer?
The tern spend the summer at its breeding grounds around the northern polar circle. It is not known how many breeding pairs of Arctic tern summer in Iceland, but the figure is believed to be somewhere between 250,000 and 500,000, which means there are 2-3 times as many Arctic tern as humans in Iceland!
What kind of food does an Arctic tern eat?
By moving continually between the Arctic summer and the Antarctic summer, the Arctic tern sees more daylight than other animal on Earth. Arctic terns feed in shallow coastal waters on small fish such as sand-eels, and nest on beaches and offshore islands.
Are there any Arctic terns that have failed to breed?
Arctic terns completely failed to breed in some areas. In the Shetland Islands, which usually have more than 20,000 pairs of Arctic terns, not one chick survived.

Arctic Terns are social birds, foraging in groups and nesting on the ground in colonies. They often rest on ice and fly on graceful and buoyant wings. Migration is the best time to go looking for an Arctic Tern, unless you have plans to visit their arctic breeding grounds or their Antarctic wintering grounds.
What kind of courtship does an Arctic tern have?
If this goes well, Arctic tern courtship moves to the ground and involves strutting and posturing with their wings held open. Once paired up, Arctic terns build nests together in small depressions in the ground. Males then continue to fish for their females.
