Abstract

Moose (Alces alces andersoni) of Central British Columbia can be rapidly sexed during helicopter aerial surveys to obtain population composition after bulls have lost their antlers. Cows, when seen from behind, exhibit a white vulval patch on a solid black background; bulls show no patch. Secondary sex characteristics, such as snout color and bell shape, have also proved useful in sexing adult moose.
