Arctic Tern
Sterna paradisaea
Native Range: Eurasia and North America
Notes:
migrates circumglobally and hence is one of the world's longest-distance migrants, nesting in the Arctic and "wintering" in the Antarctic; accordingly, probably sees more total hours of daylight during the year than any other species on Planet Earth; very similar to the Common Tern but has noticeably shorter legs at rest; no sexual dimorphism.
