WE called them “Ghost Deer” where I grew up in the north woods.
One did not ‘advertise’ where one was seen. Most hunters will not shoot a ghost deer, not only because it’s illegal, but it’s considered bad luck.
I had a big buck that would go through my woods down here - I haven’t seen him for a few years. Deer population here is WAY down due to coyotes. Those I hear running though my woods at night, in packs, running deer. I hate to hear it.
“We called them ghost deer where I grew up...’
I can imagine at night... with some mist, they would look ghostly.
