Flight exercise this morning
Osprey Kalakotkas Pandion haliaetus
On the fifty-second day of life courage was mustered and several tours around the nest were made but there have of course been flying exercises earlier too.
Young ospreys fledge in their 50th to 55th day of life so this is a quite normal performance.
