Out-Of-Season Births Of Elk Calves In Wyoming, Bruce L. Smith

United States Fish and Wildlife: Staff Publications

ive out-of-season births of Rocky Mountain elk were documented over a 24-month period at the National Elk Refuge, Wyoming. One of four November neonates was radio-instrumented and subsequently died seven days later due to hypothermia. An April-born calf was killed by a coyote. Supplemental winter feeding of elk at the Refuge may increase the frequency of asynchronous reproduction.
