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.

An article about breeding of Short-toed Eagles in Surendranagar District /map/ has been published in the Indian BIRDS – Journal of South Asian Ornithology this year. Such releases are always of great interest because observation data on Indian Short-toed Eagles are rarely available on the Web:
