The die-off of bighorn sheep from pneumonia led Montana wildlife managers on Monday to take the unusual step of abruptly closing a hunting season tied to a wild herd near Yellowstone National Park whose seasonal mating rituals attract scores of wildlife watchers. The emergency closure came after state biologists estimated that pneumonia had claimed nearly 40 percent of a herd near Gardiner, Montana, whose numbers fell to 55 this month from 89 last year, state wildlife managers said on Monday. Such pneumonia outbreaks have been linked to contact between wild sheep and domestic ones that graze on public allotments and private lands across the Rocky Mountain West. More than 1 million bighorns once roamed the region but their numbers had fallen to just tens of thousands in the first decades of the 20th century because of unregulated hunting and disease, according to the Wild Sheep Foundation.
