Circaetus gallicus information navigator

Guilad Friedemann reports on observations of 3 Short-toed Eagles tagged with number colour rings in the Judean Foothills /map/ in 2011 and 2012 (Grey 62, Orange 3 and White 14). Those Short-toed Eagle males have been photographed by different observers this year at the age of 7 and 8 CY. Small photo galleries are represented on Guilad’s FB page with his brief explanations and comments (Iw):

For example, the male tagged as "Orange 3" is fully adult, although, his parents are still active, continue to hold the territory and breed. It is always a great pleasure for a researcher to know that chicks found and ringed in the past, in spite of many dangers, have become the magnificent adult snake eagles, to see them now as virtuosic fliers, ultraprecise spotters, looking like amazing semi-mythical creatures in the end.

The next live broadcast of the same Short-toed Eagles’ nest in the Judean Foothills /map/ has been started by Guilad Friedemann and the team on April 4^th. As in the two previous years, the stream can be watched on the Israeli Birding Portal. More details are available on the Israel Raptor Nest Cam Facebook page.

The recently accepted article of Guilad Friedemann and others is a result of the study of interspecific interactions between Short-toed Eagles and Long-legged Buzzards and their breeding in the Judean Slopes /map/:

Guilad Friedemann and the team started the live stream of another nest of the same Short-toed Eagle pair in the Judean Foothills /map/ this year, since April 2^nd. As well as last year, the broadcast is available on the Israeli Birding Portal. For more details, also, please visit the Facebook community page of the Israel Raptor Nest Cam project.

Results of a comparative study of using foraging resources by Short-toed Eagles and Long-legged Buzzards in the Judean Foothills /map/ are reported in the following fresh article of Guilad Friedemann & others:

This year Guilad Friedemann and the team managed to start a new live broadcast from another nest of Short-toed Eagles in the Judean Foothills /map/. The video stream is available on the Israeli Birding Portal. A short history can be viewed on the Facebook community page of the Israel Raptor Nest Cam project.
