Why do sooty terns have to fly all the time?

Sooty terns sometimes take little 1 or 2-second naps when flying. They have to do this, since they cannot float and there is nowhere to land to sleep when at sea. Sooty tern feathers can become waterlogged because they are not waterproof, so they spend a huge amount of time at sea constantly flying.

When did Carl Linnaeus describe the sooty tern?

How long does a sooty tern stay out of sea?

It feeds by picking fish from the surface in marine environments, often in large flocks, and rarely comes to land except to breed, and can stay out to sea for 3 to 10 years. Due to the lack of oil in its feathers, it cannot float, and spends that entire time on the wing.
