cheers for that Dave, have just spent a pleasant hour watching these magnificent birds, I would say yes that's what I saw, I wish I had seen the underside of the bird as it seems more uniform than the back, also I think the light makes a big difference, the first vid I watched the bird looked the wrong colour, but when I saw one flying in full sunshine, it was a lot more red looking like the one I saw, which was also in bright sunshine, I am now pretty sure I saw a goshawk near to my home in Bristol, which is very exciting to me, thanks to everyone for answering
