| Summary: | ABSTRACT. Packs of arctic wolves, Canis lupus arctos, travelling with pups were seen in August or September in Polar Bear Pass, Bathurst Island, Northwest Territories, in five of eight years of field observations. One pack with five pups was observed in 1977 over a period of 19 days. The activity of the pack was centred around the sites of two recently killed muskoxen. Adults took pups to a new kill only the day after the kill but did regurgitate meat for them within 2 hours. Adults and pups continued to use kill sites for up to 8 days after depletion of food available at the carcass. Pups were left on their own at the sites for 8-55 hours at a time. The pups travelled without adults between the kill sites and up to 5 km away at rates varying from 2.5 to 10 b h- ’. Pups travelled as fast as 11 b h- I over longer distances when with adults. The observed time of extensive travel with the pack was earlier than for most southern wolves. The use of kills as temporary rendezvous sites after the pack has begun travelling provides not only a place to meet, but allows pups to rest, feed, explore, and gain experience while adults continue hunting. |
