Not sure about all the other guesses but I have been up close and personal with a very young and thin black bear that vaguely resembles that shape. The tan around the nose area looks very similar to the young bear I saw, and the one I saw was only slightly larger than this animal.
Its hard to tell from the camera shot, but small black bears are this thin, depending on whats around to eat, but my opinion is a very young, not a cub, black bear. The only thing Im basing it on is the tan around the snout.
Could be just about anything due to the array of critters, and species of animals in the wild, but panther, yote, and others could very well be true, but from my VERY vivid memory of my run in with a black bear last year, its not far off, but this is my opinion only!
