Large grazers

It is early in the morning, the sun has just risen. Time to go hunting. A cold wind is blowing harshly across the barren plain. Only grass and a few small bushes around you, as far as the eye can see. Perfect for the large grazers you and your fellow hunters are going for today. A group of wild horses moves along the horizon, but you leave them alone for now. Today you go for the jackpot: a woolly rhinoceros.
