First horses, then guinea pigs now birds!

Did you notice if it had a forked tail or not? If not then that would rule out a young red kite (probably wrong area anyway). Other than that it could be a young buzzard but that’s about as far as my knowledge goes. It does look like a juvenile though which won’t make things any easier for you. You really need Brigantesnation to have a look at it, I think he knows about these things.
