Not 100% on this by any means but I figured this would be worth posting to get some second opinions. We’re definitely not in prime badger habitat but looking at photos of badger burrows on google and it seems like a much better guess than an armadillo or something. The “skirt” of dirt around this was quite large, and there was even a second hole a little beyond the edge of the larger one. Might try and borrow a trail cam to confirm.

My nephew spotted this while we were doing a bird survey on Feb 4th. He noticed it as we drove by and said, "stop that might be a badger den!" This den, or sett, didn’t appear to be in use... no fresh dirt, tracks or sign of recent digging associated with it. What do you mammal experts think?
