Ferruginous Duck
Local status: Very rare vagrant
The identification of this Aythya is fraught with difficulty due to the similar appearance of hybrids between other Aythya species. The lack of deep water and large flocks of Pochards A. ferina and Tufted Ducks A. fuligula in the York area possibly explains why this species is rarely recorded
