Arctic Tern migration mapped in unprecedented detail 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 species is strongly migratory, seeing two summers each year as it migrates along a convoluted route from its northern breeding grounds to the Antarctic coast for the southern summer and back again about six months later. Over its lifetime the record-breaking tern could be flying as far as 3 million km between the Farne Islands and Antarctica, the equivalent of nearly four trips to the moon and back. The main evolutionary basis for Arctic Tern migration and bird migration in general lies in the fact that it has to be genetic. 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). Breeding birds sport a full black cap, short red legs, and a red bill.

The data was obtained by placing miniature archival light loggers (Also known as geolocators) on a number of breeding Arctic terns in 2007 - 50 birds in Greenland, and 20 in Iceland. The loggers work by recording and storing ambient light intensity, which in turn reveals information on sunri… 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.

Here, they feed on zooplankton and fish to fuel themselves for the long journey ahead. "They make a detour of several thousand km but once we start comparing the route to the prevailing wind system, it makes perfect sense - moving in a counter-clockwise direction in the Southern Hemisphere, and clockwise in the Northern Hemisphere. The Arctic tern's extraordinary pole-to-pole migration has been detailed by an international team of scientists. About half the birds that were tracked decided to take the South American path.

But rather than retracing their southward flight paths, the birds follow a gigantic "S" pattern up the middle of the Atlantic Ocean. "The use of these devices on seabirds is not only revolutionising our understanding of migration patterns, but the resulting data on distribution also help address the requirement to identify important biological hotspots," said Richard Phillips from BAS, a co-author of the PNAS paper.
