A Hawk Entered The Eagles "NO FLY ZONE"

I was just about to leave the Bald Eagles nest sight when a hawk intruded on the eagle's self imposed "no fly zone". The eagles were perches several trees away from their nest. I saw the hawk out of the corner of my eye and as I was turning my camera to the hawk the eagles appeared. Both eagles flew up at the hawk. I chose to follow one of the eagles. Exciting sequence. Needless to say, the hawk vanished into the clouds.
