A Black Bear attacks the Bluebirds. Sleeping in the bird house were 4, almost-mature, Bluebird nestlings. A camera inside the house captures the nestlings' traumatic experience. They were tossed and turned as the bear pulled the house to the ground and rolled it repeatedly as he chewed, clawed and stood on the box.
We saw this attack, viewed from outside the house, in a prior post. Miraculously, the nestlings survived!
