I got curious due to the wild horse controversy so I looked into other wild (or feral) horses around the world. I found several but no list, so I made my own and put it on squidoo. However I'm stumped on the names of those two. I found a website to the canadian ones but the hawaiian horses I only found indirectly. I wouldn't even have thought to look if not for the Wild Horse Island, Phantom Stallion series.
There are more than I was expecting!
