| Résumé : | A male Falcated Duck Anas falcata in Devon in winter 2006/07 was a subject of much debate in terms of the bird's age. Research on the subject involving the study of captive birds and museum specimens concluded that the Devon bird was a first-winter male.The wider results of that research, concerning the moult and ageing of this species in autumn, are presented in this paper. |
