Well Eric as you know I am from that area and would have to say those are diffently black rat snakes which are native to your area. The banded pattren showing threw is a died give away.
David I was thinking black rat at first as well but the smooth weekly keeled scales makes me think its a pair of Eastern Rats... Black rats have heavier keeled scales with a much duller and less patterned look...
They are going to be either full blown black rats or an intergrade between black & grey rat. I have seen tons like that around here. Some black rats keep pattern(due to just the locale or intergrading), and others are almost completely black. I just can't see them being anything else, but the two I mentioned above. Remember black rat snakes are eastern rats. They went through a name change a couple of years back. I believe they used to be called elaphe obsoleta, and now are called Scotophis alleghaniensis. I wish they never would change this shit and keep it simple.
You are correct Gregg. I really should have added that fact to my first post. they are eastern rats the northren rats seem to have more yellow pigment that shows threw on there sides. (just my thoughts by the way, I can be proven wrong very easliy on the yellow pigment as I havn't done alot of research on this) And I really don't know about the scales. As a local we always just refer to them as black snakes and the other common native species in that area is the black racer which you can easily id as a diffrent snake because of the nice even shade of black with no pattern showing and the bright white sides. Oh and the easiest way I have found is a black rat will run when they see you and a racer will stand its ground for the most part. Gotta love those pissy ass racers
This is not true technically... There the differences that I mentioned... At one point Easterns were bundled into the "black rats"... However the scalation does differ and true black rats have virtually no patteren...
