The charge of the ducks

Up at Swinsty reservoir this morning, I was surrounded by a large group of inquisitive ducks. They are obviously used to people up there feeding them scraps from their picnics. One duck seemed rather interested in my bike tyre, and was having a go at it. Maybe it thought something tasty was stuck to it......
Just as I was about to take this picture, someone to the left threw down some scraps (of bread I think) and there was a sudden charge to get there first. 
It's been quite overcast today with grey skies. This shot, therefore, gets nominated for a blip rather than anything scenic. That's my second duck blip in 7 days!
