Rut in zoology means an annually recurring sexual excitement in animals during the mating season. Particularly in the deer family, which include elk. When the males are active. History of the world dates back to the early 15 century, from the Old French word rut (“noise, roar, bellowing”, ruit, from Late Latin rugitus, from rugire (“to roar”). The male in the picture had just gotten ready after rolling in mud and his urine, with his antlers all decorated. Bugling as he made his way to the ladies.
