Detailed explanation-1: -Because arctic terns do not fly in a straight line, the distance they fly every year is even longer than the approximately 30, 000-kilometer (18, 641-mile) from Arctic Circle to Antarctic Circle. This makes the arctic tern’s migration one of the longest of any animal on Earth.

Detailed explanation-2: -Caribou have the longest terrestrial migration, but there is more to the migration story. A grey wolf from Mongolia has been documented as having traveled over 4, 500 miles in a year. Caribou are often credited with the longest terrestrial migrations in the world, though without much scientific support.

Detailed explanation-3: -Arctic terns spend about four months of the year in active migration between their summer breeding area and overwintering grounds. Their southward migration typically takes place during the fall months, while their return trip takes place in the spring.

Detailed explanation-4: -No bird migration list is ever complete without mentioning the record-breaking feats of the Arctic Tern. By far the longest migration known in the animal kingdom, this medium-sized bird travels 90, 000 km (55, 923 mi) from pole to pole every year-from Greenland in the North to the Weddell Sea in the South.

Detailed explanation-5: -Arctic Tern Smashes Record For Longest Migration Ever By Flying 96, 000 Kilometers. The astonishing migration of the tiny Arctic tern has just set an incredible new record.
