Changeable appearance of Short-toed Eagles in picturesFeb 21, 2019 / Comment
Please look through the series of photos of Short-toed Eagles taken by Bernard Joubert in Haute-Loire /map/ in the past few years, showing the impressive variability of their appearance:
Snake eagle is one of the most elegant raptors in Europe. When observed at close range, one is amazed by the way it can change looks and attitudes. This can clearly be seen in these pictures taken in France (Massif central) in 2009, 2012 and 2016.

Circaetus gallicus on Raptors ID websiteSep 29, 2018 / Comment
This WordPress site is dedicated to identification of Raptors in the nature. The main idea was to provide easy uploading various pictures of birds of different age and sex, then, to describe and categorize them correctly, developing in this way a rich database for Raptors identification. All photos of any species can be found by one click, ones of Short-toed Snake Eagle as well. Descriptions of sex and age-related features are in English and Catalan.
A report on the rehabilitation of a Short-toed EagleJun 30, 2018 / Comment
Although, this paper is rather old, it can be considered as a good example of a report on Short-toed Eagle rehabilitation. If all similar cases were described in such a detailed way, our knowledge on sexing and ageing of Short-toed Eagles would be much deeper:
• Theo van de MORTEL, 2006 – Voor het eerst een Slangenarend Circaetus gallicus geringd in Nederland [Male Short-toed Eagle found emaciated in The Netherlands in May 2006] // De Takkeling, 14 (3): pp. 232-235. – (Nl).
The article is available on the Natuurtijdschriften site now.
Observations of ringed ST Eagles in Israel in 2018Jun 28, 2018 / Comment
Guilad Friedemann reports on observations of 3 Short-toed Eagles tagged with number colour rings in the Judean Foothills /map/ in 2011 and 2012 (Grey 62, Orange 3 and White 14). Those Short-toed Eagle males have been photographed by different observers this year at the age of 7 and 8 CY. Small photo galleries are represented on Guilad’s FB page with his brief explanations and comments (Iw):
For example, the male tagged as "Orange 3" is fully adult, although, his parents are still active, continue to hold the territory and breed. It is always a great pleasure for a researcher to know that chicks found and ringed in the past, in spite of many dangers, have become the magnificent adult snake eagles, to see them now as virtuosic fliers, ultraprecise spotters, looking like amazing semi-mythical creatures in the end.
