Firefighters in Colorado received an unusual phone call on Thursday.  Parks and Wildlife colleagues informed them that they had tranquilized a black bear that climbed up a tree in a residential neighborhood.  The problem was that the bear, instead of falling from the tree, had climbed higher and gotten stuck.  A firefighter solved the problem by climbing up a ladder and giving the sleeping bear a little nudge.  Luckily, the bear came falling down onto a tarp below.
