An unusual deer appeared in Yellowstone National Park, USA. He was photographed by a remote monitoring camera.
In the video, you can see how the animal performs something like dance – bounces and spins on a knoll between the trees. Him actions are not like a game or a nuptial dance because others animals are not visible nearby. At some point, the deer stopped and looked towards the camera, as if feeling that behind him peeping, but soon began to frolic again. Biologists could not definitely say why the animal behaved so weird way. But the web users had a lot of versions, among which are diseases, annoying flies and ordinary fun.
