What animal sees the most daylight and has the longest migration of any on earth? This would be the Arctic Tern, recently back to Alaska and from Antarctica.
Sleek and swift, their body styles are fitting; terns look the part of a long-distance athlete and their wings cut through the air as if by magic.
Even after a pole-to-pole migration, the birds spend most of their time on the wing, diving and eating in the air, even sleeping aloft with one eye open.
