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.

Returning of Short-toed Eagle to Poland
Apr 29, 2013 / CommentAfter 153 days of silence GSM transmitter of the adult Short-toed Eagle female tagged in Poland in 2012 started working again in Africa on March 1st. So, Polish ornithologists could mark her spring migration route receiving coordinates of her location each hour. The route was different from the autumn one: the bird visited Greece and Ukraine where she was travelling during almost 3 weeks, maybe because of the bad weather conditions, but finally she achieved the old breeding territory in Poland /map/. Her partner was observed there on April 17th with caught snake in his beak. The female joined him 2 days later.
You can find more information about the project on the Lublin Ornithology Society website and you can see detailed descriptions of the Short-toed Eagle’s adventures on the LTO page in Facebook (Pl). Also please view the migration map:

Winter observations of Short-toed Eagle in Crimea
Feb 10, 2013 / 1 CommentThe following observations have been made for the first time in the history of studies in the Crimean Peninsula. The point, Cape Chauda /map/, is located strictly at the 45th parallel.
While counting geese on Cape Chauda in the southern part of the Kerch Peninsula (Crimea, Ukraine) we have observed a young Short-toed Eagle (aged less than 1 year) on January 14, 2013. Then at the same location two individuals (male and female) in juvenile plumage too was observed on February 4, 2013. The birds were kept on a power pole surrounded by steppe.
Weather conditions in the autumn and winter of 2012/2013 years were soft, positive temperatures dominated, snowfall was rare and only for short periods. Observations in January and in February were made at above-zero temperature as well, snow cover was missing. Perhaps such weather conditions have caused Short-toed Eagles’ wintering in Crimea.
Possible prey items on Chauda: Steppe Viper (Vipera renardi); the snake is common there, but in warm winters can be active and can appear on the surface of the ground – we have seen them in previous winters; also voles couldn’t be excluded.
New article on sexing of Short-toed Eagle nestlings
Jan 21, 2013 / CommentWe offer you the summary (En) of the following article dedicated to sexing of Short-toed Eagle and Common Buzzard nestlings:
• Jalby V., Malafosse J. P., Nore T. et Wink M., 2012 – Détermination, par la biométrie, du sexe des poussins chez deux espèces de rapaces Circaetus gallicus et Buteo buteo. Comparaison avec les Autours des palombes Accipiter gentilis et les Buses variables adultes [Nestling sexing by biometric and molecular analysis in two diurnal raptors, Circaetus gallicus and Buteo buteo. Comparison with the Goshawk (Accipiter gentilis) and adult Buzzards] // Alauda, 80 (3): 187-202.
The biometric data on Short-toed Eagle nestlings were collected by Jean-Pierre Malafosse in Cévennes National Park /map/.
Story of Short-toed Eagle ringed by Francesco Petretti
Jan 20, 2013 / CommentA story of life and death of one Short-toed Eagle ringed by Francesco Petretti in Western Central Italy /map/ in 1989 is represented below:
The eagle was born on the 18th of May 1989 in Tolfa Hills, 40 km north of Rome. The parental pair built the nest on a very large deciduous oak tree covered with ivy on the north facing slope of the hill, at 400 metres of altitude.
On the 27th of June 1989 P0845 reached the maximum weight of 1,800 grams, then the weight decreased, as it is usual among fledging eagles in the study area, and on the 17th of July, when the eagle left the nest, she weighed 1,680 grams. She was fitted with a backpack radio for ground telemetry and moved within the home range for a couple of months. Contact with her was lost on the 20th of September 1989, when the eagle probably left the area to reach the wintering ground in Africa.
On the 16th of September 2012 the body of P0845 was found dead at a distance of only 9 km from the ringing site. The body was brought to the Raptor Center in Vico Lake Nature Reserve, but death causes are unknown. P0845 was at least 23 years and 4 months old and I suppose this is a longevity record for the species.
