Dreaming of Nuts?

Saw this squirrel up in a tree, and got my Lumix from my pocket, zoomed out and grabbed this blip, with a view to it possibly making a nice silhouette. But when i downloaded it, the squirrel is sleeping! who knew that????
I thought it had immobilised itself in the hope I wouldn't spot it, but no, it was asleep, and as soon as I quietly stepped forward in the hope of a second shot, it was gone like a flash!
Sorry the picture quality isn't brilliant, i've cropped it down too which destroys the clarity a lot, but its interesting, anyway
