just watching two little birds quietly from window outside a tree in the backyard with children, a little bird jumped out of the nest and fell on the ground, the mama bird was flying back to help. Suddenly a big black bird flew over and took the little bird away. MaMa bird followed the big bird immediately. We were shocked, and immediately jumped out of the house, and yielding..too late! The big bird took the little bird flying away... My kid is crying hard...blaming me how could we do not help the little bird...
