I'm going through a few received pictures from my trail cams and I get to these two images of a small mammal in the small beech tree on the right. My first thought is that it is just another squirrel, but then I realized the bright patch of white, the tail, and the posture of a weasel.
Here's a cropped version: It still seems kind of squirrel like, but that white patch all the way up to its chin tells me it is not a squirrel. Squirrels do have a whitish color on their bellies and necks, but the color on this animal is bright white and goes the whole way along the underside of the animal. The tail hanging down is a bit bushy for a weasel, but long and thin for an eastern gray squirrel.
