Jun 14, 2015 / Comment

Some news about the migration of ST Eagles in the Italian Peninsula.

They all are dedicated to observations of migratory birds of prey in the Apuan Alps /map/ during several consecutive seasons, including records of numerous Short-toed Eagles:

This spring Egidio arrived in his birthplace again. This is a young male Short-toed Eagle fitted with a satellite transmitter in Regional Park Gallipoli Cognato /map/ in 2013 within the project which had been started with participation of Ugo Mellone yet in 2010 and later continued by Giuseppe Lucia.

 

Ecology and ethology of Short-toed Eagle, 1980

Feb 27, 2015 / Comment

Circaetus gallicus (drawn by F. Perco from a photo)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:

The article is available on the Museo di Scienze webpage.

Presentation on feeding ecology in Central Italy

Dec 26, 2013 / Comment

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.
