Status and Trends

Population size and trends and patterns of distribution based on BTO surveys and atlases with data collected by BTO volunteers.


This species can be found on the following statutory and conservation listings and schedules.


We have no population estimates for this scarce species.


Ferruginous Ducks mostly winter in southern Britain with clusters of occupied 10-km squares around Chew Valley Lake in Avon, the Thames Valley, Norfolk Broads and the East Midlands. They generally associate with Pochards, with which they are likely to make local movements, so these clusters of sightings may relate to a single bird visiting nearby sites within and across winters.
