Many thanks to Guilad Friedemann for kind information about a new project of the KKL Fund – HD Web camera at a nest of Short-toed Eagle in Israel /map/. The online stream and a brief description of the project are available in Hebrew now, the English translation will appear soon. Besides, you can find texts about Guilad’s research in English and in Hebrew, view current data on observations of STE in the country and enjoy a video recently recorded with the installed camera; more clips are also listed on this page now. So help you Google Translate!
UPD May 1st, 2015: the Facebook community has been created for uploading and watching video clips made with the camera.
The following detailed article dedicated to ecological and ethological aspects of biology of Short-toed Eagle had been published 35 years ago. The text addresses a variety of topics and can be of great interest to anyone who is studying the species. It is printed on 87 pages, has many beautiful pictures and includes data on distribution and conservation of STE on the Italian Peninsula:
• Silvio BRUNO, Fabio PERCO, 1980 – Considerazioni ecologiche ed etologiche sul Biancone (Circaetus gallicus) [Ecological and ethological considerations on Short-toed Eagle] // Natura bresciana, vol. 17: pp. 124-210. – (It).
The article is available on the Museo di Scienze webpage.
These fragments of Short-toed Eagles’ flights have been shot at their breeding territories and hunting grounds in Kiev Region /map/ and in Mizhrichynskyi Park /map/ this year. The video is commented on, please, pay attention on subtitles. You can see eagles A11, B11, K11 and L11 in the clip. Certainly, also other more melodious names were given them for routine use. These STEs occupy their breeding sites within the same home ranges from year to year since at least 2006 and 2010. For a regular observer every bird has obvious individual traits. The video without compression can be downloaded.
Francesco Petretti reports the findings of a long term study of the feeding ecology of two populations of Short-toed Eagle in Western Central Italy /map/: Maremma Regional Park /map/ and Tolfa hills. In both areas snakes represented the bulk of the diet, but there were significant differences in the selection of prey species with a higher number of “not-conventional prey species”, e.g. mammals and toads, in Maremma Regional Park and a stronger predation on Hierophis (Zamenis) viridiflavus in Tolfa hills. The study is in progress and will be implemented in 2014.

The presentation is published on the Stazione Romana Osservazione e Protezione Uccelli (SROPU) website. It contains tables, diagrams and beautiful photos of Short-toed Eagles and snakes.

…and an abstract of next one is placed on a website of Ardea – the official scientific journal of the Netherlands Ornithologists’ Union:

Part with aggregation: You can see here the special phenomenon in my study area /map/, where many Short-toed Eagles flying over one field (aggregation) that is being worked up by a tractor, waiting for the prey (mainly rodents!) to be exposed by the tractor so that they dive quickly on the prey.
Part with Short-toed eagle chasing a rodent: You can see here a Short-toed Eagle chasing a rodent (Gerbil) that has succeeded to get out of a ploughing, and after a relatively long pursuit the Eagle managed to get it.
Catching a rodent: here you can see another part where Short-toed Eagle gets a Field Vole in his talons (you can even hear the rodent screaming).
