Like most terns, the Arctic tern has high aspect ratio wings and a tail with a deep fork. [19] The adult plumage is grey above, with a black nape and crown and white cheeks. The upperwings are pale grey, with the area near the wingtip being translucent. The tail is white, and the underparts pale grey. Both sexes are similar in appearance.
The Arctic tern migrates the greatest distance of any bird. Seabird migration is similar in pattern to those of the waders and waterfowl. Some, such as the black guillemot Cepphus grylle and some gulls , are quite sedentary; others, such as most terns and auks breeding in the temperate northern hemisphere, move varying distances south in the ...
Path integration in mammals makes use of the vestibular organs, which detect accelerations in the three dimensions, together with motor efference, where the motor system tells the rest of the brain which movements were commanded, [25] and optic flow, where the visual system signals how fast the visual world moves past the eyes.

The Arctic Aircraft Arctic Tern (named after the bird) is a bush plane that was produced in small numbers in Alaska in the 1970s and 1980s. It is a strengthened and modernised version of the Interstate Cadet of the 1940s. It is a high-wing braced monoplane with fixed tailwheel undercarriage. It has two seats in tandem, with the rear seat ...
A flyway is a flight path used by large numbers of birds while migrating between their breeding grounds and their overwintering quarters. Flyways generally span continents and often pass over oceans. Although applying to any species of migrating bird, the concept was first conceived and applied to waterfowl and shore birds.
Charlotte McConaghy's Migrations is the story of Franny Stone, an Irish-Australian woman who wants to track the last flight of the Arctic terns — birds who migrate from the North Pole to ...
Some species extend this strategy to migrate annually between the Northern and Southern Hemispheres. The Arctic tern has the longest migration journey of any bird: it flies from its Arctic breeding grounds to the Antarctic and back again each year, a distance of at least 19,000 km (12,000 mi), giving it two summers every year.
