This gallery consists of photos taken by Sergey Domashevsky in period of 2010-13 during his expeditions to some regions of Ukraine and of Central Asia. Sergey is an expert of Ukrainian Birds of Prey Research Centre, his main activity is aimed at research and conservation of birds of prey in Ukrainian Polesie such as Spotted, Short-toed Eagles and other species of raptors and owls. As always, some explanatory comments can be found below the presented images.
The phenomenon of Short-toed Eagles’ hunting aggregations was studied by Sameh Darawshi since 2005. Yesterday Ron Milgalter took these video clips of about 30 Short-toed Eagles together, which hunt fleeing small mammals and reptiles above an agricultural patch while the tractor was ploughing the field /map/.
The following text is available now on the Spanish Herpetological Society website:
• A. Acuña Rodríquez, F. Martinez-Freiría, G. Velo-Antón, 2013 – Ingesta de tres especies de herpetos (Bufo calamita, Anguis fragilis, Vipera seoanei) por un ejemplar de águila culebrera (Circaetus gallicus) abatido en un parque eólico [Three species are found in a Short-toed Eagle killed by wind farm] // Boletín de la Asociación Herpetológica Española, vol. 24(1): Pre-publication, ms685. –

This gallery contains some photos of Short-toed Eagle taken in Northern Ukraine this year. As usual, it is planned to be updated with new pictures if I manage to take something interesting. They may be not as of high quality as of interest for Short-toed Eagle watchers. That is why all of them are commented in detail. Single eagles are named individually with alphanumeric code, for example: “A11” means bird “A” of the gallery of 2011, but “A” without a number here means that the individual has not been marked yet in previous galleries.
Please visit a website of Francesco Petretti – www.francescopetretti.it. It is updated weekly and you can find on it reports about observations of Short-toed Eagles in Central Italy /map/ containing some photos of them. There are several ways to get information on the subject: to search by keywords, for example, «Circaetus»; just to use the tags, such as «Short-toed Eagle» or «Biancone» etc.
