Vermont Fish and Wildlife officials are warning the public to beware of grumpy bears. The fickle winter weather has exposed bear dens, prompting the bears to awaken from hibernation routines, wildlife experts said. Officials said they have fielded reports of bears at bird feeders and roaming across residential areas. Wildlife officials told the Burlington Free Press that rabbit hunters should be especially cautious because the disrupted bears will often bed down in evergreen thickets. They also warned hunters, hikers, and skiers not to follow bear tracks, saying some bears may be travelling with newborn cubs.
