Eric L. Geist L. David Mech 1992 <p>Seventeen Wildlink capture collars were tested 61 times on 18 gray wolves (<i>Canis lupus</i>) during 1989-1991 in the Superior National Forest of northeastern Minnesota. Overall success rate was 89%, and most failures were attributable to premature battery expiration. When batteries were changed ≤ every 2 months, 17 of 17 tests succeeded. With an upgraded version of the collar in which batteries lasted longer, 17 of 18 tests succeeded. Over the 2-year study, 6 of the 17 collars were lost. For serially recapturing individuals, the Wildlink collar proved useful and reliable if care was taken to replace batteries at proper intervals.</p> application/pdf en U.S. Fish and Wildlife Service Field testing the Wildlink Capture Collar on wolves article
