| opmerkingen | 16 October, De Hamert, Bergen, Limburg, first calendar-year, photographed (J E Kikkert et al). With the ongoing decrease of the western population combined with regular hybridization with Lesser Spotted Eagle A pomarina (cf Lontkowski & Maciorowski 2010), the identification of these two eagle species has not become any easier, especially since most records concern fly-bys. The CDNA therefore developed a review protocol. Baseline of this protocol is that several but not all hybrid features need to be judged in order to rule out a hybrid with reasonable certainty. No hybrid features were found in the first bird, whereas the excellent photographs of the second ticked all the right boxes for a pure bird. Annual Report 2016. | |
