Sorry but cannot see anything in the photograph

There are two birds in the photo; a Buzzard type raptor in the bottom left quarter, and a falcon in the top right corner.
I don't think that it's possible to confirm either based solely on the features visible in this photo - although I see nothing to suggest the larger bird isn't a Common Buzzard. The bird in the top right looks more like a Hobby to me though, because of the swift like silouette.
