It is simply a White deer, not an Albino. Here is a quote from Outdoor Life Magazine to give all a better insight, I lived in that region for many years and it was a common local discussion -
"Another piece that I found particularly fascinating centered around New York’s Seneca Army Depot which, at the time, was home to the world’s largest herd of white deer.
“The story begins in 1941 at an army depot in Seneca County, NY when some soldiers noticed a couple white deer roaming inside their 24-square-mile fenced-off base,” explains blogger Dylan Thuras. “Realizing that something strange (and wonderful) was afoot, the General ordered the soldiers to protect the white deer. While the soldiers continued to hunt brown deer inside the confines of the reserve, the white ones were allowed to breed. With predators were kept at bay by a giant fence, and pressure put on the brown deer by hunting, the white deer population was able to explode. (These blanched deer are not albinos, as you might assume, but rather possess two copies of another rare recessive gene for whiteness.) There are now 200 of them roaming the grounds, the largest herd of white deer anywhere in the world.”
