wow, that's beautiful. And being in velvet, even the antlers are white. I had a quick google to find out a bit more, and the white moose are only found in Varmland. There's a little bit about them here: The White Moose of Sweden Side-note: they have no protection so are just as open to being shot during the hunting season as any other moose in Sweden.
That's probably the most bizarre 'White' deer I've ever seen- it looks like an apparition. I'm used to seeing white fallow deer, even white Red deer and more recently, white Sika too, but not Moose. Like all white deer they must present an easy target.
