After its excursion far north (Netherlands) Sardona has been spotted again in its former release area at Calfeisen. This is another prove for the enormous potential of the bearded vultures to roam over large distances.
During the last weeks at least two young Bearded vultures have been spotted in the Netherlands.
One of them was Sardona. Thanks to the help of many colleagues and ornithologists we know that the male bird (released in Switzerland 2010) ranged in the border area between Belgium and the Netherlands on 13. and 14. of June.
The other bird had no marks. It seems to be a wild born bird coming from the Alps or the Pyrenees.
