The astonishing migration of the tiny Arctic tern has just setan incredible Modern record book . While it has long been known that the sea birds make the titanic head trip from the northerly cerebral hemisphere to the southern , and back again every year , raw data from bird trace from the north of England have just smash the record for the total aloofness flown . Researchers have find out some birds fly a monolithic 96,000 klick ( 60,000 miles ) on a rotund trip .
The researchers trail the snort flying from the Farne Islands in northeastern England , down the west coast of Africa , across the Indian Ocean , make land fall down in Antarctica , and then postdate the coast to finally make it to the Weddell Sea , before turning around and coming back again just in time for their training season . This means that in totality they flew for 96,000 km ( 60,000 miles),beating the previous recordset by a bird tail from the Netherlands by 5,000 kilometre ( 3,100 miles ) . And all this by a dame weighing just 100 grams ( 3.5 ounces ) .
“ It ’s really quite humbling to see these lilliputian Bronx cheer return when you deal the huge distances they ’ve had to journey and how they ’ve battle to survive,”explainsDr . Richard Bevan of Newcastle University ’s School of Biology . “ Further analytic thinking of the data from these trackers will allow us to get a better understanding of how the Arctic Terns organize their migration and how spheric climate change may affect their routes . ”

The enquiry was carry out by scientists at theUniversity of Newcastle , for the BBC programSpring Watch , which charts the fortunes of native British wildlife . Last yr , the research worker tagged 29 birds with geolocators in the Farne Islands , and then expect with baited breath for their return . So far , they deal to catch 16 of the tagged birds , which have given up their epic migrant secret , but four others with their geolocators still attached have been spotted , which will add up even more data .
The Farne Islands , located off the sea-coast of Northumberland in northerly England , are a vitally important site for ocean birds . In add-on to the 2,000 pair of Arctic terns that stock there , it also hosts around 23 other specie of sea birds , and in incredible numeral . Over 87,000 pairs of birds lay their ball there last twelvemonth , including 50,000 pairs of guillemots and 35,000 pairs of puffins , all crowded onto the spits of rock that jut out of the sea . In gain to the birds that take reward of the rich North Sea , more than 1,000 gray seal pups are also born there each year .
For those in the UK , Spring Watch broadcasts on BBC 2 at 8 p.m. local time every weekday evening until June 16 . The little birds ' amazing story will be diffuse tonight , or you could catch up on BBC iPlayer , to see the storey in full .
