Larger than a pochard, the male has an orange-brown head with a red beak and pale flanks. Females are brown with pale cheeks. In flight they show whitish primaries. They dive, dabble and up-end for their food. There is a large population in Spain and nearer but smaller numbers in France, Netherlands and Germany - and occasional wild birds may come to the UK from the Continent. The UK breeding birds almost certainly all come from escaped birds.
