FILE - This undated file photo provided by the Idaho Department of Fish and Game shows a cub black bear burned in the Mustang Fire north of Salmon, Idaho. The cub is recovering and may be released in June, an Idaho wildlife sanctuary an official said. The four-month-old bear nicknamed "Boo Boo" was discovered by a fisherman in a tree along the Salmon River in August days after the 312-square-mile Mustang wildfire complex passed through the area. The cub had second-degree burns on all four paws and was malnourished when U.S. Forest Service and Idaho Fish and Game workers rescued it.
