and tension between rival males increases. Once a potential mate has been found the male enters the display stage of the stage which lasts one to three days. During this time he will court the female by standing sidewise three to five yards from the female moose to show himself as a mate. If successful he will get to mate with her for several days and then move on to a new partner. This pattern of behaviours will then repeat with successive mates until late October or early November. Following the mating season, bull moose spend long hours resting and feeding before forming their usual winter groupings. Although the battle between males is the main contest, there is also a battle between females. Usually, this occurs between an older cow moose and a younger female. The mature cow will attempt to stop the younger one from coming near to the wallow in a vicious attack with her forelegs and if the younger female gets to lie in the wallow the older female will drive her out of it only to return to lie in it and take up as much space as possible. During this event the bull moose will not interfere and he will just watch in plain sight. Other mammals Sexual behavior of impalas Further reading See also Lek Notes Weiss, John.
