The first significant sighting that we had were these two bull elk out on Black Tail Deer Plateau. Male elk shed their antlers each year, typically in February or March. While they do not have horns, or while their new ones are growing in males will often travel together in groups which affords them some extra protection while they are more vulnerable. Later in the year, when the antlers have grown out, the males become more competitive and tend to travel alone until they gather a harem together in the fall during the rutting season.
While the antlers are growing they are covered with a thin layer of skin that is called velvet. The velvet is filled with capillaries that bring blood to the antlers which help them to grow. At the end of the summer the the antlers harden and become solid bone. Since the velvet is no longer needed it begins to peel off, often with the help of a small bush or tree.
We did see a lot more cow elk then we did bulls, other then yearling males, or spikes as they are called, traveling with the cow herds. The cows seem to be more weary of people then the bulls or the bison are, or maybe they just don't like to have their picture taken like the one above who we photographed near the Madison River on our way out of the park on Wednesday evening.
