Where I am in The States, we had a goat get away from a "petting zoo", and started to hang out with the deer on public and private land.
I remember the first time I saw her ...I was wondering what the heck I was looking at, at a distance. She was very light in color, so several of us made sure not to kill her, as she would give away the location of the deer she was with LOOONG before the deer with their natural color blending in with the woods were close enough to see. All one had to do is keep an eye on her as she was almost bright white, and easy to see at a distance in the woods, and simply wait for her to get close and then just look hard and you could spot her deer friends.
Then some yahoo thought it a good idea to harvest her since she wasn't considered a "game animal" there were no regs stopping him, and he was a manure-tastic "hunter" (imho) and couldn't get a deer...
Lately there have been five Zebra... yep Zebra..., running around in Maryland. Another Zoo escape. Folks killed some of them too...
