Seventeen Wildlink capture collars were tested 61 times on 18 gray wolves (Canis lupus) 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 .ltoreq. 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.
