The Arctic tern flies the longest route of any bird in the world, when it migrates from the Arctic to the Antarctic each year.

Arctic terns have the longest migration of all - a round trip of up to 35,000 km (22,000 miles) each year! In early Fall, they fly back South to the Antarctic region where they spend the Winter (blue).
The genetic link is most evident in the way birds choose their routes and also site fidelity.

During its life, an Artic tern may fly more than 2.4 million km (1.5 million miles). A small, slender gray-and-white bird with angular wings, the Arctic Tern is well known for its long yearly migration. The team, which worked in collaboration with BBC's Springwatch, tagged 53 adult Arctic Terns on the Farne Islands, Northumberland, over a three-year period. A Newcastle University-led team has mapped the route and stop-off points during Arctic Tern's record-breaking 56,000-mile annual migration to an unprecedented level of detail, using data from electronic tags retrieved from 47 terns..

The main evolutionary basis for Arctic Tern migration and bird migration in general lies in the fact that it has to be genetic. Breeding birds sport a full black cap, short red legs, and a red bill. Map of Arctic Tern Migration Routes - Photo Credit: USFWS map by Michael Langlois For years, seabird biologists have wanted to study Arctic tern migration between breeding colonies in Maine and their wintering grounds in the Southern Hemisphere.

The Arctic Tern goes ‘south’ for the winter – if going to Antarctica is considered ‘going south.’ Range: Due to its long distance migration, this bird’s range is quite large. The Arctic Tern migration is quite an impressive journey considering that they fly almost from Pole to Pole, covering up to 10,000 miles each way. 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 small but mighty flyer is well known for its long-distance migration, traveling each year from one end of the world to the other and back. The main goal is to present the research results of the first ever scientific study to use tracking devices to follow a full annual cycle of Arctic tern migration. The study of long-distance migration provides insights into the habits and performance of organisms at the limit of their physical abilities. Migration route of the Arctic tern 11 / 20 Interpolated geolocation tracks of 11 Arctic terns tracked from breeding colonies in Greenland (n = 10 birds) and Iceland (n = 1 bird). The average spring migration was 13,988 miles (average of 472 miles/day). Friends of Coquet Island Coquet Island is the only island left in the UK where you can still find a breeding population of roseate terns. Bird Behavior Like a lot of other birds, arctic terns eat fish. In the spring it migrates from Antarctica to the arctic and subarctic where it breeds. [Image] It breeds in the southerly reaches of the Arctic and winters in the Antarctic, making its migration a round-trip of 60,000 to 82,000 km (roughly 37,000 to 51,000 miles).

Arctic Council , Conservation of Arctic Flora and Fauna Working Group (2001) CAFF Map No.34 - Migration routes of the Arctic Tern. When it was time to return to the breeding colonies, the birds seemed in more of a hurry and all took the same general route back to Maine. It travels from its Arctic breeding grounds to Antarctica where it enjoys the Antarctic summer, covering around 25,000 miles.

The arctic tern is a slender bird with narrow wings and short legs.
It travels from its Arctic breeding grounds to Antarctica where it enjoys the Antarctic summer, covering around 25,000 miles. This makes the arctic tern’s migration one of the longest of any animal on Earth.
