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.

Short-toed Eagles in Northern Ukraine, 2017 (part II)
Feb 28, 2018 / Comment
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 out of thousands of pictures taken with the main purpose to regularly identify local Short-toed Eagles individually have been selected for the represented gallery.

Bernard Joubert’s article on communication of ST Eagles
Dec 10, 2017 / Comment
The following paper by Bernard Joubert on Short-toed Snake Eagle communication abilities was recently published:
• Bernard JOUBERT, 2017 – Circaète Jean-le-Blanc : des "mots" pour le dire [Short-toed Eagle: "words" to tell] // Rapaces de France, n° 19: pp. 54-55. – (Fr) {rough translation}.
The summary
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.
GPS-GSM tagging of Short-toed Eagles in Hungary
Oct 14, 2017 / CommentWithin the framework of the Turjánvidék LIFE project, which aims the preservation of habitats of such species as the endangered Hungarian Meadow Viper (Vipera ursinii rakosiensis), two Ecotone GPS-GSM trackers were bought in 2016. The main aim was to follow the life of a Short-toed Eagle pair residing close to and hunting regularly on viper habitats. Since the capture of the adult male failed in 2017, experts marked the offspring
of this pair with the transmitter /map/. The chick was named Örs, an ancient Hungarian name meaning «human», «man» or «hero» but also a name of a Hungarian tribe from ancient times.
Örs left the natal area on October 1st and its tracks can be followed on SATELLITETRACKING.EU.
The other transmitter was deployed on a repatriated individual in 2016, which died two months later in Poland. Its tracks are not available on the aforementioned website yet, however, another post will appear here if so.
