Male elk bugling during the fall rut. Large male elk are known as bulls. Male elk have large antlers which are shed each year. Male elk engage in competitive mating behaviors during the rut, including posturing, antler wrestling and bugling, a loud series of screams which is intended to establish dominance over other males and attract females.

A brown pelican preening, reaching with its beak to the uropygial gland (preen gland) near the base of its tail. Preen oil from the uropygial gland is spread by the pelican's beak and back of its head to all other feathers on the pelican, helping to keep them water resistant and dry. Adult winter non-breeding plumage.

Humpback whale lunge feeding on Antarctic krill, with mouth open and baleen visible. The humbpack's throat grooves are seen as its pleated throat becomes fully distended as the whale fills its mouth with krill and water. The water will be pushed out, while the baleen strains and retains the small krill.

Courting pair of southern right whales underwater, Eubalaena australis. While the posture in this photo isn't quite mating, it is a courting behavior that often precedes mating. The male is below, upside down and trying to access the female belly-to-belly. However, the female does not want to mate, so she has positioned herself upside down at the surface so that the males in the courting group cannot reach her genital slit.

Courting group of southern right whales, aerial photo. Mating may occur as a result of this courting and social behavior. The white whale seen here is a serious player named El Copulador (the copulator) and is often seen in mating and courting groups of southern right whales at Peninsula Valdes. His light coloration is an indication that he was a white calf, but he did not darken as he aged in the way most white southern right whale calves do.
