Circaetus gallicus information navigator

Two papers about effects of the wind and the large water surface on Short-toed Eagle migration have been prepared by Spanish and Italian researchers and released this year:

One more contribution from Guilad Friedemann. This time it is a video presentation. Using Google Earth tools Guilad invites us to follow David, one of the Short-toed Eagles tagged with the special GPS-loggers, from his home range in the Judean Foothills /map/ to the wintering grounds in Sudan. The virtual tour on his migration route is amazing!

After 153 days of silence GSM transmitter of the adult Short-toed Eagle female tagged in Poland in 2012 started working again in Africa on March 1^st. So, Polish ornithologists could mark her spring migration route receiving coordinates of her location each hour. The route was different from the autumn one: the bird visited Greece and Ukraine where she was travelling during almost 3 weeks, maybe because of the bad weather conditions, but finally she achieved the old breeding territory in Poland /map/. Her partner was observed there on April 17^th with caught snake in his beak. The female joined him 2 days later.

You can find more information about the project on the Lublin Ornithology Society website and you can see detailed descriptions of the Short-toed Eagle’s adventures on the LTO page in Facebook (Pl). Also please view the migration map:
