Résumé :	The Ferruginous Duck Aythya nyroca has recently declined over much of its native range. It is a rare winter visitor to Britain and Ireland, currently averaging about 13 records a year, with higher numbers in occasional influx years. Most occur in England and it is very rare in Ireland, Scotland and Wales. It is concluded that most records relate to wild immigrants. Identification is discussed, with particular reference to similar-looking hybrids.
