A Trial Translocanon of Sandhill Cranes

Wild-trapped sandhill cranes (Grus canadensis pratensis) captured and moved to habitat occupied by cranes 152 miles away did not return "home" and were seen near the release site up to 20 months later. The frequency that the translocated birds were seen near the release site indicated that dispersal had been minimal and that restocking in suitable habitat might be done with relatively few wild-trapped cranes. Dispersal behavior is an Important factor m restockmg success with wildtrapped animals and determines the minimum number of individual animals required. To measure dispersal behavior in sandhill cranes in anticipation of future restocking efforts, we trapped and moved cranes from high population areas to other occupied crane habitat. We thank M. J. Fogarty and D. W. Peterson for help in capturing some of the cranes.
