I find that squirrels are often difficult to photograph. We have a State Park just outside our town. If you happen to come across one, before you can get a photo of it, about nine times out of ten they will run up the back of a tree.
You have to shoot them from a concealed position. That's why I shoot through my office window. They don't know I am there, or they are so used to me that they don't perceive me pointing a camera as a threat.
