The mating season of Moose. During mating season bull Moose dig rutting pits in the ground with their hooves, urinate in the pit, and then roll in the urine to cover themselves with this natural 'perfume' in order to help attract cow Moose.
"The Rut" is the period of time when antlered ungulates, such as deer, sheep, elk, moose, caribou, ibex, goats, pronghorn and Asian and African antelope, mate. The rut for white-tailed deer usually lasts from 1-3 months in the northern hemisphere and may occur most of the year in tropical zones. The Rut is triggered by a shortening of the length of daylight hours (referred to as photoperiod) each day.
