KNOB

Apparently that's one of the collective nouns for wigeon (Anas penelope), one of my favourite birds. Others are 'trip', 'company' and 'bunch' (which is what I generally call collections of beasties when I can't think of the proper term, and now I'm vindicated). There's a mallard too. I didn't know until this morning that it's only the female mallards that have the laughing quack, or that this mallard might be a visitor from Russia! The things you learn on Tweet of the Day!

Out of focus as I was taking it from the car, at a distance, in pouring rain.
