Occurred on July 11, 2018 / South Bend, Indiana, USA
Info from Licensor: "On this morning, I was at work at my clinic, doing some reading on the rooftop terrace and enjoying the morning sun. Suddenly there was a loud “thump” and I turned to see a beautiful red-tailed hawk, looking intently at its reflection in the glass doors! I took some photos and then began to video-record this amazing occurrence. The hawk was completely transfixed by his reflection and attempted to fly forward several times, not recognizing that he was seeing a reflection. After some time had passed, and several futile attempts to fly through the glass had been made, my “visitor” gave up, puzzled and flew away."
