In the winter Terns go to the northernmost points of Antarctica.
Breeding grounds of terns range in type and include islands, boreal forests, rocky beaches and tundras.
After migration the terns spend their winter on pack ice and during this time the terns undergo a mold and lose most of their feathers.
Arctic terns mate for life and form large breeding colonies where several pairs nest together.
Each Arctic summer, these birds return to their preferred nesting areas, find their mates, and breed.
The amount of Arctic terns that are left in the world is around 2 million Arctic terns.
Arctic terns are very long lived birds and many Arctic terns can reach 15 years to 30 years old.
The Arctic terns eat small marine invertebrates and mainly small fish.
The Arctic tern is a tern in the family Laridae.
Arctic tern birds have a circumpolar breeding distribution covering the Arctic and sub-Arctic regions of Europe, Asia, and North America.
Arctic terns are also so lightweight with small bodies, short legs, and narrow wings that they can glide through the skies on a breeze.
The beaks and feet of an Arctic tern are bright red, and their bodies are covered in gray and white feathers with a cap of black feathers on their heads.
Arctic 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.
Summer weather is also usually calmer at sea, allowing the birds to fly more easily
Arctic terns can also be seen along the eastern coast of South America, Western Europe, Iceland, Australia, New Zealand, and on Pacific islands.
Their winter habitat extends to the northernmost points of Antarctica.
Breeding grounds range in type and include boreal forests, islands, tundras, and rocky beaches.
Arctic terns mate for life and form large breeding colonies where several pairs nest together.
Each Arctic summer, these birds return to their preferred nesting areas, find their mates, and breed.
The Common Tern drinks on the wing, dipping its bill in the water with its wings held up.
They can drink saltwater or freshwater—like many seabirds, they have nasal glands that excrete excess salt.
Common Terns made an unfortunate appearance in women's fashion in the late 19th century.
Arctic terns usually are shorter-legged and have more extensive dark markings on the outer edge of the outer primaries than do Antarctic terns.
In addition, immature Arctic terns have a marked dark carpal bar, which is absent in Antarctic terns.
It is possible that the Arctic tern experiences more daylight than any other animal on the planet due to their migration patterns.
Arctic terns are so lightweight that they are able to utilize ocean breezes to carry them long distances without flapping their wings.
They are able to sleep and eat while gliding.
