Field testing of commercially manufactured capture collars on white-tailed deer

We conducted 31 tests of commercially manufactured capture collars on female white-tailed deer (Odocoileus virginianus) in the Superior National Forest, Minnesota, under temperatures from -37C to 22C. Deer were recaptured in 28 of the 31 tests; in the 3 failures, we remotely released the collars from the deer. Communication with the collars was achieved from up to 3.0 km on the ground and 26.5 km from the air.
