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.

Text of Yves Boudoint

Feb 4, 2007 / Comment

One of works of the oldest Short-toed Eagles researcher in France – Yves Boudoint /map/ – is represented below. This text describes some interesting details of biology of the species and includes notes on some traditional and untraditional methods of study:

• Yves Boudoint, 1953 – Etude de la biologie du Circaète Jean-le-Blanc [Study of the Short-toed Eagle biology] // Alauda, 21 : 86-112. (Fr).

Short videos. Aggregation and rodents

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).
