BAS sent out a press release<\/a> about a paper that confirms they have the longest animal migration in the world. New information on bird migration was revealed by an international team of scientists who confirmed that the Arctic tern flies more than 70,000 km on its annual migration trip from pole to pole \u2014 the equivalent of three trips to the moon and back over its lifetime. Scientists were able to map the migratory movements using the tiny tracking instrument known as a geolocator, which was developed by BAS scientists.![\"image001\"](\"http:\/\/www.racingyachtmanagement.com\/blog\/wp-content\/uploads\/2010\/01\/image001.jpg\" "\\"image001\\"")
<\/p>\nThis simplified figure shows migration patterns of the Arctic tern, from the breeding sites in Greenland and Iceland to the winter grounds at Antarctica. After initiating the southbound migration (yellow line) the birds pause their migration in the central part of the North Atlantic (small circle) for almost a month before they continue towards the wintering sites at Antarctica (large circle). In spring, the northbound migration (white line) is conducted more than twice as fast in a gigantic ‘S’ shaped pattern through the Atlantic Ocean. Areas particularly rich in biological productivity are indicated by yellow and green colours.<\/p>\n
I mentioned this in the dive boat and of course the marine biologists had lots of smart allack comments on how could a bird fly where there was no oxygen etc. but everyone did agree that it was a pretty amazing and hard to comprehend – those little birds have seen a lot!<\/p>\n","protected":false},"excerpt":{"rendered":"
The terns are nesting on all the ridges at the moment so when we are ridge walking we have be careful not to tread on their nests. When we are out on the boat they swoop around us sometimes following us for a ways.
