Mule Deer

Mule Deer

Most female mule deer conceive during their second year and give birth in June or July, though the time of birth will vary according to the environment.

Most female mule deer conceive during their second year and only rarely during their first year. Ovulation occurs about 12 to 14 hours after estrus terminates. Approximately 27 to 29 days elapse between conception and implantation.

The average gestation length for a mule deer is 204 days and the peak birth period is estimated to be from June 16th to July 8th, though the time of birth will vary according to the environment. A 305-meter rise in elevation has been associated with a 7-day delay in the birth period.
