They're found in red woods and at the snow biome. Make sure to take precaution when approaching as these biomes are pure danger. I recommend to have a small perimeter around it to keep it from running away and keep most carnivores out.
In Genesis this is an impossible tame to keep alive. For instance, since it has a large turn radius it with go near a therazinasaur or a gigantopithacus and die. Trust me, in the attic before you have tech and a bird, it’s hard.
