Investigations on the aetiology of pinching off syndrome in four white-tailed sea eagles ( Haliaeetus albicilla ) from Germany
International audience The purpose of this study was to investigate the aetiology of the pinching off syndrome (POS), a generalised feather abnormality affecting free-living fledglings of the white-tailed sea eagle ( Haliaeetus albicilla ) (WTSE) in Europe. For the first time, extensive clinical, ha...
