Résumé
I monitored female desert mule deer (Odocoileus hemionus crooki) (n = 7) with radio telemetry in the Belmont and Bighorn mountains, Arizona, 1991. I examined habitat use, size of seasonal ranges, predation by coyotes, and behavior, and I identified fawning and fawn rearing habitat. Female desert mule deer preferred the montane vegetation associations and avoided creosote flats (Larrea tridentata) during fawning. Size of seasonal ranges were smaller in the 2 weeks postpartum (X = 3.75 km2 than in the 2 weeks prior to fawning (X = 6.71 km2 Activity during the first or last 4 hours of daylight differed 2 weeks postpartum and the remainder of the year (P = 0.034). Female desert mule deer were less active during daylight 2 weeks postpartum. Females during fawning were not any closer to water than the remainder of the year.
