When I awoke the bird was still there, sitting on the ground, obviously stunned from hitting the window, dead bird (aka breakfast) at his feet. I got the camera and snapped a few photographs out the window, the hawk did not notice me.
I went to the downstairs bathroom and stuck my head out the window and took a few more photographs, again, the hawk did not move. I went out the back door and stood on the deck, taking a few more photos. The hawk started eating. I moved slowly, crouched down to the cold ground in my PJs and kept clicking and moving closer a little at a time.
I got to the dog run and still the hawk did not even notice me, you can tell because when I moved or made a sound the hawk did not respond so I kept getting closer and closer, to the point that when the hawk lifted its head up to pull on the meat I clipped the head. I zoomed my 100-400mm lens to 300 and then 250. I could not believe it!
He got up on the stump and ate some more, got back down and ate some more, the concussion (?) must have really affected him and just when I was wondering if I was going to have to call a bird rescue place it finished the last morsels and flew up on a branch, cleaned its beak on the tree limb for a few minutes and flew away.
