The image is spoilt by the overall softness. Its likely from the camera techs that the softness is due to camera shake but it also looks front focussed - the shrubbery looks to be more in the plane of focus rather than the squirrel - which isn't helping the subject sharpness. With the 5D you should be able to shoot at over iso 1000 with no noise problems at all, your ISO/shutter speed is too low from the overcast light conditions for 315mm, it should ideally be 1/250s to 1/500s.
I agree with everything Mike has said. It is possible to get sharp results at very slow speeds like this, but everything has to be rock steady and that is very hard to do, you will always have lots of bin fodder. Eric
jeff be interested to know what lens this was taken with - sorry but its true he is OOF, distracting object in top right also, try again as the snow is great!
