Changeable appearance of Short-toed Eagles in pictures

Feb 21, 2019 / Comment

JOUBERT B. Changing Gallicus. 2009-2016. Haute-LoirePlease 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.

A report on the rehabilitation of a Short-toed Eagle

Jun 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:

Another subspecies of Short-toed Eagle determined

Nov 30, 2017 / Comment

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.
