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 4th. 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 compilation of the annual gallery for 2017 has been finished. Photos taken in Northern Ukraine depict well-known and new individuals of the monitored pairs. Only 36 of thousands of pictures taken with the main purpose to regularly identify local Short-toed Eagles individually have been selected for the represented gallery.

The following paper by Bernard Joubert on Short-toed Snake Eagle communication abilities was recently published:
Short-toed Snake Eagles have the rich social language, various tools which help them to express their intentions and relation to behaviour of other representatives of their species. The main problem of studying their behavioural language is defined by difficulties of correct interpretations. Besides various vocal signals, these eagles reveal a rich body language vocabulary, thanks to the extraordinary plasticity of their plumage, which is used for hovering in different airflows while hunting. Simplistically, 3 types of signals are identified: those related to movements, postures and holding of plumage.
› Examples of the gestural communication are: aggressive demonstratively slow and strong wing-beats, so-called «vulture» flights, territorial «festoon» display flights.
› Communicating through postures includes: an aggressive «albatross» posture, a posture of «angel» which is used for marking a chosen nest for the partner.
› Communicating through appearance changes at close contacts comprises states of occipital feathers and pupil size, which can express both tension and relaxation of birds.
This brief review is nothing more than an invitation to observe and puzzle out those various and subtle means of ST Eagles’ communication.
Quite many articles dedicated to Short-toed Eagle are reprsented on the ResearchGate and not yet described on our site. Currently, we’d like to mark one, which is very fresh, raising a topic of georgaphic variations at the farthest border of the species range /map/ and questioning again the concept of Circaetus gallicus as a monotypic species:
• Shengrong Nathaniel NG, Les CHRISTIDIS, Jerry OLSEN, Janette NORMAN, Frank E. RHEINDT, 2017 – A new subspecies of Short-toed Snake-eagle from Wallacea determined from morphological and DNA comparison // Zootaxa, Vol. 4358, No. 2: pp. 365–374. (En).
The abstract of the paper available now is of great interest itself.
