Squirrels are extremely difficult to photograph. They're constantly scurrying all over the place, twitching and moving around. Over the weekend I attempted to take pictures of one that fell into a trashcan:
While this one's still got a lot of issues, I think it turned out better than the first one. Before I could move over to angle myself so that the stair rail on the left wouldn't be visible, yup - the squirrel moved so that all I could see was it's rear.
