The Antarctic tern resembles closely to the Arctic tern. However, the local Antarctic Terns are in their breeding plumage when the migrating Arctic Terns arrive in their non-breeding plumage. Arctic terns also have shorter legs and more prominent black margins on the outside of their primary feathers.
What adaptations do arctic terns have?
Hollow bones for lightness. Able to sleep on the wing during migrations. Short legs that aid an aerodynamic shape in the air but make the birds rather clumsy on the ground.
How do Arctic terns migrate?
Arctic terns migrate to follow the summer sun. Seasons happen because Earth is tilted on its axis while it revolves around the sun. During winter, the Northern Hemisphere is tilted away from the sun’s warming rays. This is why it’s colder during the winter in places north of the Equator, like the United States.
What is Arctic terns habitat?

Where does the arctic tern come from?

What is Arctic tern famous for?
Famous for their record-setting migration—the longest of any animal in the world—Arctic terns are projected to lose 20 to 50 percent of their habitat due to climate change.
