A scarce duck in the county with only ten or so records. However the possibility of escapes from wildfowl collections can not always be discounted. For a list of all records go to the Bucks List
This rather smart drake turned up at Caldecotte Lake on 4th February 2016. It stayed there for several days and then moved to Mount Farm Lake on 12th February. It then proceeded to move between the two lakes periodically.
The following photos show all of the identification features of a Ferruginous Duck. While the origins of many scarce ducks is often unknown, this individual is rather wary at times and is un-ringed, so perhaps suggesting a wild origin. The Bucks records committee will decide in due course whether to accept as a wild bird or a potential escape.
