I've been seeing a larger than normal number of fawns sans their mothers this season. One is a bigger than average button buck that I saw on opening morning and several times since. He's never had a doe with him. I saw a couple youngsters (BB and doe fawn) that came by about 30 minutes before their mother. When I saw her, I originally thought she was a buck - especially when she grunted. However, her grunt caused both little ones to run over to her and they even tried to nurse her. The next morning, I saw them by themselves again.

Can't say what's causing it, but apparently it's common in MD this year.
