I sent the pictures to my cousin, who is an avid birder, who then sent them to another person who is a specialist with hawks.
This is his reply: "Head shape and light crown rule out Coopers Hawk. Stocky build suggests buteo, if I could see throat and tail it would be easy. So, if throat is clear it is a Broad-winged, if dark a Red-shouldered sub adult. My guess is Broad-wing."
Hope this helps the debate.
