I looked out my window and saw this massive bird walking around on the ground.  It was so large I actually thought it was a turkey (from a distance).  It then flew up into this tree. What you’re looking at is his backside.  When he spotted me in my window he turned his head around a complete 180 degrees. What cannot be appreciated in this image is just how large this bird is.  It had to be the largest hawk I’ve ever seen. I quickly grabbed my Nikon D7100 and put an 80-400 mm Nikon lens on it and quickly took the picture from my window.
