Terry Bowyer, John G. We retrospectively tested whether differences in activity patterns and foraging efficiency by males and females were responsible for sexual segregation in mule deer Odocoileus hemionus. These deer spatially segregated by sex during the dry season May—October , which encompassed parturition, and aggregated during the wet season November—April , which included rut. Activity did not differ among types of social groups of deer mixed-sex, adult male, or adult female , but was greater during the dry season than in the wet season. Foraging efficiency percentage of active deer feeding was greater in mixed-sex groups than in groups of either adult males or adult females during both wet and dry seasons. We rejected the hypothesis that differences in activity or foraging efficiency lead to spatial segregation of the sexes in mule deer; no aspect of that hypothesis will explain why sexes use space or other resources differentially.

Zoo Idaho - Mule Deer Fact Sheet
Sex: Female Birthday: December 13, Snickers is a wild born female mule deer. Sex: Male Birthday: April 24, Oliver was transferred to Zoo Idaho from Idaho Fish and Game after an officer confiscated the deer from a family in Nampa that was keeping it as a pet. Oliver can not be released because he is an imprinted deer. Sex: Female Birthday: June 8, Misty was transferred to Zoo Idaho from Idaho Fish and Game after it was rescued from a family in Niter, Idaho who claimed they rescued it after the mom abandoned the deer. Misty is a non-releasable mule deer. Mule deer occur over most of the North American west from southwest Saskatchewan through the western Great Plains and into parts of northern Mexico.
Debra L. Social behavior and organization of mule deer Odocoileus hemionus californicus were investigated over a 1-year period in northwestern Los Angeles Co. I analyzed 2, agonistic interactions by sex of participants.
