Moose are one of a number of species where males contend for the right to mate with their preferred female . As such , you might call back distaff European elk do n’t have much say in the subject . That ’s where you ’d be wrong .
Moose societies are polygynous , which means that male person mate with lots of dissimilar females but females only have one partner . This imply that a big , aggressive male person has an excellent probability of securing lots of partner , whereas a smaller male launch the risk of being close out wholly . The fall rut is when the generative pairings are sorted out , and often that involve a whole lot of fierce fighting between males .
So what part do female play in all this ? Well , until now , all we really knew was that they would sometimes permit out what ’s known as “ protest groan ” when a male approach them . These moans would bring other male , which would then often top to a full - on moose battle . investigator had n’t really paid attention to the protest moans , assume courtship was really being determined in the fights .
But Idaho State investigator Terry Bowyer say it ’s more complicated than that . As it turns out , the females are using some pretty dodgy strategy when it comes to their protest moans :
“ Female moose gave dissent groan more often in reception to suit by humble males , even though the large males wage in more courting . This behavior by females helped them deflect harassment by smaller male , but also provoked competitiveness between large male . Male aggression was more common when females gave protestation moans than when they did not , indicating that this vocalisation motivate male - male person aggressiveness . ”
So , with a few well - chosen groan , the female moose can make the males fight for their love . Dr. Bowyer explains :
“ Protest moans countenance females to exert some option in a mating scheme where males restrict [ that ] choice through male - male fight . We believe that distaff choice is a more critical component of mating systems in polygynous mammalian than previously thought . ”
