Red-crested pochard

Description:

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.

Notes:

Spotted in St James park in London. Not the best quality photo, but they wouldn't sit still for long enough!
