Two Short-toed Eagles together, Brassoir - 2016 / by Rémi MalignatHenry de Lestanville describes in his paper staying of 2 Short-toed Eagles at Brassoir in summer 2016 and the current status of the species in Picardy /map/:

• Henry DE LESTANVILLE, 2018 – Stationnement de deux Circaètes Jean-le-blanc Circaetus gallicus à Brassoir en 2016 [Staying of two Short-toed Eagles at Brassoir in 2016] // Avocette, 42 (1) – Revue naturaliste de Picardie Nature: pp. 3-8. – Short-toed Eagle. file (Fr).

An impressive number of ST Eagles migrating at Sarimazi, Southern Turkey /map/, in autumn 2018 is reported on the Egyptian Vulture New LIFE site: 10853. This raises a lot of questions about real strength of their streams from Eastern Europe. Many thanks to Gábor Papp for sharing!

Monitoring of Short-toed Eagle in the Cévennes National Park /map/ and Lozère was continued by local conservationists in 2017:

Bernard Joubert’s article on communication of ST Eagles

Dec 10, 2017 / Comment

Photos taken by Bernard Joubert: Short-toed Eagles' communication posturesThe 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. – Short-toed Eagle. file (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.
