When the Seneca Army Depot in upstate New York was shut down in 2000 it left an odd legacy: the world’s largest herd of white deer. The fence erected around the facility in 1941 happened to enclose a few white-tailed deer that carried a recessive gene for all-white coats; the depot commander forbade his GIs to shoot any white deer, and eventually the white herd grew to number more than 300.

These are not albinos; they have brown eyes, not pink, and they live alongside some 600 brown white-tailed deer. In 2016 the Army sold the depot to a local businessman, and part of the land has now been established as a conservation park. Bus tours have “turned out to be hugely successful.”
