Piebald or Albino, what do you think?

[LittleBen]

Leucistic for sure. We had quite a number of those on Long Island. Remember seeing two together in the woods once and thinking at first glance "who the heck put a giant propane tank out here in the woods!"

That was until the gas tank split in two and started running ... had to sit for a seconds after that.

The deer is neither Albino nor Piedbald but instead leucistic. Another mutated phenotype.
