The former Seneca Army Depot in upstate New York is home to a rare herd of white-tailed deer, all of which carry a recessive gene for all-white coats.
The Seneca white deer are not albinos, they are a natural variation of the white-tailed deer, which are usually a brown color. These rare deer are leucistic, meaning they lack pigmentation in the fur, but their eyes are the normal brown color. In the wild, the very visible white coat makes these rare creatures easy targets for both human hunters and predators like coyotes, but this particular herd was protected by a 24-mile (39 km) fence erected around the Seneca Army Depot in 1941. They were isolated inside the depot perimeter and since the military commander there forbade soldiers from shooting the white deer, their number grew into the hundreds.
