Alaska Study Finds Female Moose Manipulate Males to Fight

Moose-mating season, just around the corner in Alaska, means crisp fall days, ripe berries on the bushes and, according to a new study, animal behavior that might seem more at home in a rowdy singles bar.

Female moose, or cows, are able to manipulate amorous males into fighting each other, allowing the more desirable bulls to emerge as mates, according to the study, which is based on observations made in Alaska’s Denali National Park.

The cows’ efforts are subtle, so they have long been overshadowed by the belligerent, antler-clashing behavior of bull moose in rutting season, said the study, which published by the academic journal Behavioral Ecology and Sociobiology.

“Because we have so much aggression in the big males, it actually masks female choice,” said Terry Bowyer, a biologist at Idaho State University and one of the study’s authors.

Female moose use protest moans to ward off small male suitors, the study points out.

Bowyer and his study partners found they also use those protest moans when approached by some big suitors, setting off fights between large bull moose.

Another hot Colorado summer is slowly coming to a close in the high country. Aspen leaves are beginning to change color, elk calves and deer fawns have nearly lost their spots, and reports of bear sightings are slowing down. Most of the osprey chicks have fledged and are now nearly identical in size and plumage to their parents. I’m ready for the fall – looking forward to watching the moose and elk in rut and listening to bugling bulls and cow calls.
