Short-toed Eagle. Bernard Joubert. 2009

Area: southern Auvergne. Altitude: 870 m above sea level. Tree: pine Pinus sylvestris. Height: 6 meters.

The egg was laid near the 8th of April, the hatching happened around the 24th of May. The young bird took off the 30th of July, early afternoon. He was 67 days old. It was the twelfth succesful take-off in this site in 14 years.
The first visit – very discreet-happened when the chick was 10 days old. Between the 21th of June and the 30th of July, nine observatory sessions (circa 30 hours). Here is a photografic summary.
