This little fat hog was out and hunting early mourning, in air temps of 56F. Which is the coldest in the field temps to date.
I observed one individual crossing the road at 54F and another at 58F. All early mourning events.
Of course, in the fall, the mass temps in the ground are much warmer then the air temps. In the spring, the mass temps are much colder then the air temps.

This lite colored hognose was found 5 days earlier in the same area as the brown one. Just showing some natural contrast.
