Attempt to Cross-Foster Gray Wolf, Canis lupus, Pups into Another Wolf Pack

Posted on

We attempted to cross-foster four 18-19 week-old Gray Wolf (Canis lupus) pups into another Wolf pack 182 km from their natal pack territory. The pup introduction was the result of depredation control on a farm in northwestern Wisconsin. Three pups died within 14 days of release. A fourth pup survived along the edge of the new pack territory over winter, dispersed in the spring, joined or formed a new pack and was captured on a depredation complaint four years later.
