In response to the CM reader that has spotted a white deer with black spots, it is most likely a piebald deer. This is caused by a rare genetic mutation that causes the deer to lack the pigment that gives it hair its color. There are varying degrees of piebald and I have seen some with brown and light black spots. It is not to be confused with albinism. The piebald deer still has normal eye color.

Here in Keltner we usually see one slightly piebald deer per year with either two white legs or one white leg. I believe about 1 in 1000 deer are piebald to some extent. To see a melanistic deer would be a rare treat, however. There are about 1 in several million of those, and they are entirely black.
