The white deer found at Seneca Army Depot are a natural variation of the white-tailed deer (Odocoileus virginianus), which normally have brown coloring. The Seneca White Deer are leucistic, meaning they lack all pigmentation in the hair but have the normal brown-colored eyes. Albino deer, which lack only the pigment melanin, have pink eyes and are extremely rare. The Seneca White Deer interbreed freely with the brown deer in the former Depot and appear to share the habitat equally. Some of the white bucks show a flattening, or palmation, of the antlers, but are physiologically similar in most other ways.
More information about this deer population - Please note that this appears to be a closed system — the resident deer are confined within a fenced area that was formerly a military depot, which has enabled this uncommon condition to become prevalent through inbreeding. Should we allow this to remain a closed system? Eventually we can only imagine that the gene pool will be weakened due to constant inbreeding (the bucks are already showing signs of this). The deer have seemingly been confined within this location to facilitate the growth of the white deer population so that humans can enjoy them. Is this ethical? I think that this is an interesting wildlife management issue.
