While the mating season, or rut, for moose peaks between late September and early October, mating behavior can already be observed. It is widely known that male, or bull, moose often paw a pit in the ground, urinate in it and then stomp in it in order to splash their underside, slap the urine with their antlers to disperse it, and lay down in the pit and wallow in their urine, soaking their undersides and neck. Their pungent urine serves as an aphrodisiac for female, or cow, moose, which are attracted to the pheromones it contains. A cow will enter a wallow, aggressively displacing the bull at times and even drink his urine.
However, it’s not just bull moose urine that attracts the opposite sex. The urine of a cow in heat (defined as the two days of their estrous cycle when they will allow a bull to mount them) is equally as attractive to bulls. At this time of their reproductive cycle cows frequently will urinate in the water and along the shoreline of lakes and ponds (look closely at photo).
