I don't know what this is, and it apparently doesn't stay long because the wildlife camera doesn't take any more photographs on this night, as it would if the animal had remained in view. I suppose it's possible that what looks to be a longer tail could simply be a part of a bear's body that is partially obstructed by the vegetation. But it looks like something a little smaller than a bear, and like something that slinks along the ground, such as a weasel. I don't know what it is.
