Feather

I left Tim to mess with the Pluto drip thing today - I had other ideas in my head that I wanted to photograph. So here is one of the feathers we found in a field on a walk a while back. We've got quite a few of these - I think most are between 1 and 2 inches long, all with much the same colour and pattern. The owner had been dispatched by a bird of prey and there was nothing left but a pile of these feathers. I have no idea what it might have been though. All suggestions welcome.

Extra: UFO water droplet by Tim.
