Isle Royale’s new black wolf moves away from others, GPS tracker shows why

…The remote island and national park in Lake Superior saw its longtime wolf population of two rise to 15 over the past several months, the result of an effort to bring in more wolves from Canada and Minnesota…One black wolf was net-trapped on mainland Ontario, and the remaining six were caught on Canada’s Michipicoten Island Provincial Park, where they had been facing starvation. A preliminary look at that tracking data showed they were finding food and starting to explore. It also showed the black mainland wolf caught last weekend wanted to be far away from the other new arrivals…early GPS showed the black wolf in the latest batch preferred to put some distance between himself and the Michipicoten wolves. Park staff said that mainland wolf was in the best physical condition of all the predators caught last weekend. All new wolves destined for Isle Royale are vet-checked, weighed and tagged before being released. The six wolves taken off Michipicoten were believed to be the last of their kind on that island. Caribou, once their main prey, had disappeared from the island in northeastern Lake Superior, leaving only hares and beavers as their food options. This left some of them in poor physical shape. But Isle Royale park staff hope the new arrivals will take to moose-hunting.
