Yes, most likely mange, either demodectic or sarcoptic, but there are other possibilities, particularly since mange can be very difficult to identify just by looking at the skin. A skin scraping is needed for a positive ID on mange. Severe flea infestation can also bring on skin problems such as dermatitis which is another possibility. A third, and less likely possibility, is skin problems from poor diet or food allergies. Thyroid problems can also cause skin disorders that resemble your photo. Without running blood tests, such as a T-4 or general health profile, or taking a skin scraping to look for mange mites, it is very difficult to tell from just looking at a photo exactly what it is. However, the bottom line is that it needs help to survive, especially since it already seems to be affecting the eyes, which is essential for survival in the wild. Kt

We searched all over for prints, but the ground is too hard. So far as I know, raccoons don't make those kinds of noises, but I don't know. I thought it was a fox until it started clicking and charged. I want a game cam. :)

Stick with creamy, not chunky. Some of the 'natural' kinds have a lot of oil at the top of the jar.I volunteer at a rescue & we stuff Kongs with pb, then freeze them & give them to the dogs for their afternoon snack. All that oil makes the pb just slide out of the Kongs and it really makes a mess. We get a lot of the natural kind & we just can't use it.

There is a gray treefrog (Hyla versicolor) as well. That's the trill sound that happens twice.
