Pandionidae:
The Osprey differs in several respects from the other diurnal birds of prey, and has always presented something of a riddle to taxonomists. Here it is treated as the sole member of the family Pandionidae, and the family listed in its traditional place as part of the order Falconiformes. Other schemes place it alongside the hawks and eagles in the family Accipitridae—which itself can be regarded as making up the bulk of the order Accipitriformes or else be lumped with the Falconidae into Falconiformes. The Sibley-Ahlquist taxonomy has placed it together with the other diurnal raptors in a greatly enlarged Ciconiiformes, but this has more recently turned out to result in an unnatural paraphyletic classification. |
