Garden Squirrels

From my desk in my room I've got an unimpeded view of the squirrels. They run absolute havoc in the garden - often in the morning I see one on them playing with a local bird, chasing each other through the trees.
This afternoon one of them had an absolutely massive nut - bigger than it's head. I was a bit concerned for it since I think it must have been some sort of fake nut, but then he dropped it anyway while trying to heave it up the tree..

I get frustrated with my camera taking photos of animals (or people) moving, so here is one of him standing still..
