Bill & Steve,
I live in the Tidewater area. Around here, most of the adults show very little pattern. I also lived outside of Richmond at one time, and the Black Rats I found there also showed very little pattern.
I will have to take some head shots for you of the BK's from four eastern states. I see that they differ in eye coloring.
I remember seeing posts of western Black Rats with red colored eyes. Is that common for Black Rats from west of the Allegheny Mountains?
Bill, I also have noted the faint broad stripes (very faint but there) that can be seen between the scales. Maybe Burbink was right about lumping Eastern Black Rats, Yellow Rats, and Everglades Rats as one species.
Rick
