8 February 2012 - The Arctic Tern Sterna paradisaea
(listed under Appendix II of CMS and on AEWA) makes an incredible
migration each year. These small birds travel distances
of more than 50,000 miles, from pole to pole, crossing through
temperate and tropical regions along the way.
Arctic Terns are categorized as threatened
or as species of concern in certain countries, while BirdLife
International has considered the species to be at lower
risk since 1988, believing that there are approximately
one million individuals around the world. The Arctic Tern
has a circumpolar range, breeding in the Arctic and subarctic
regions of Europe, Asia and North America as far south as
Brittany, France and Massachusetts, USA. It is a trans-equatorial
migrant, and during the boreal winter the birds can be found
throughout the Southern Ocean to the edge of the Antarctic
ice and the southern tips of South America and Africa.
Carsten Egevang used geo-locator tags to
track ten of these terns, and he shows us how they fared
on this fantastic video. To see the video click here.
