Circaetus gallicus information navigator

How different reproduction of different pairs can be? Some adult Short-toed Eagles occupy the same sites from year to year. They had yet been identified in 2011 by photos taken since 2006 and according to previous and new observations. The birds had got indexes A11, B11 etc. although, in spoken communication we give them more harmonious names: for example, K11 is Barry, B11 is Ospry, and so on. Then later pictures of the individuals repeatedly got into the annual photo galleries. The natural identifying details are general plumage patterns, shapes of heads, wings, beaks and general silhouettes in flight from certain angles as well as signs of moulting. The number of the examined images should be enough to select the details and to collate them. Thus, now it is possible to compare the mean reproduction – – of pairs of individuals identified from year to year for certain, definitely without replacements of mates and without clear differences in objective conditions for breeding.

The following new paper describes the relation of Short-toed Eagle population to the availability of natural habitats which are being used by them as breeding sites in the Judea region of Israel /map/:

Thanks a lot to Dr. Motti Charter for sharing the file!

Short-toed Eagles in Cévennes National Park /map/, review for the previous year:

• Jean-Pierre et Isabelle MALAFOSSE, 2014 – Le Circaète Jean-le-Blanc, résultats pour 2014.

Thanks a lot to Jean-Pierre and Isabelle for sharing the remarkable results of their outstanding large-scale work in the region!

Many thanks to Guilad Friedemann for kind information about a new project of the KKL Fund – HD Web camera at a nest of Short-toed Eagle in Israel /map/. The online stream and a brief description of the project are available in Hebrew now, the English translation will appear soon. Besides, you can find texts about Guilad’s research in English and in Hebrew, view current data on observations of STE in the country and enjoy a video recently recorded with the installed camera; more clips are also listed on this page now. So help you Google Translate!

UPD May 1^st, 2015: the Facebook community has been created for uploading and watching video clips made with the camera.

Among a lot of videos of Short-toed Eagles published on the Web during the last several years some short films deserve special attention. For example, this one was made by Claudio Borghini in collaboration with Assuntino Amici, Luigi Marozza and Massimiliano Proietti in 2013. The researchers used an automatic camera having wide-angle lens and placed in immediate proximity to an aerie of Short-toed Eagles. The nest had been found in the Regional Park of Castelli Romani /map/ for the first time ever. It is evident that the method of monitoring nests using automatic cameras is becoming increasingly popular.

We try to not miss an appearance of papers about Short-toed Eagle on the Web. Every freely accessible article is added to the collection, a kind of specialized library. Certainly, the majority of them aren’t new, but they are not of less interest due to this. The following ones can be viewed on websites of the journal of ornithology Tichodroma and of Sovon.nl, Dutch Centre for Field Ornithology:
