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.
The excellent online database featherbase.info contains high resolution photos of bird feathers, various statistical data on their dimensions, useful comparing tools which allow to identify species with high confidence. Also, you can add pictures of your own finds there. Specific information on Short-toed Eagle is available on the separate page.
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.
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.
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.
One more collection of amazing moments of Short-toed Eagles’ nesting life in Croatia are brought to your attention. Please, note: both mates of that pair are coloured very typically for their sexes. This excellent gallery of pictures and videos taken by a nature photographer Ante Karanušić can be viewed on his site.
