Certainly possible. I have not seen any cases where it appeared to be significant.
Most of the mistaken identity cases I have read about involved shooting at noise, or mere movement. Sometimes they involve a successful hunter carrying a deer, the person shoots at the deer and hits the hunter carrying it.
In Wisconsin, these sort of cases were reduced to almost nothing by the requirement to wear florescent orange during deer hunting season.

Exactly right. Me too.
