I can't wait for these lovely ducks (Aythya fuligula) to return to the local park - I tried in vain to get good shots of them 6 months ago, and by the time I got suitable equipment, they'd gone. This group was far out on the water at the RSPB reserve, but I like the colours. Three pochards and a coot can also be seen.
