A plan to reintroduce the lynx to southwestern Colorado’s San Juan Mountains is running into some grave problems — four of the 13 cats released in February and March have died of starvation and a fifth was recaptured in an emaciated state. The project of the Colorado Division of Wildlife had initially intended to move 100 lynxes from Canada and Alaska to Colorado over the next two years. The Canada lynx feeds primarily on snowshoe hares and the reintroduced animals apparently haven’t found enough hares in the area and don’t adapt easily to hunting other prey.
