An augur buzzard maybe? Not completely sure so would wait for someone more knowledgeable to say for sure.
No, not a buzzard. It's 100 % a falcon but not sure which species and maybe it's even an hybrid because they are bred in quite large numbers now-a-days.
I agree with vogelcommando. If I were forced to guess, I'd say it's a hybrid and part saker, but I could be wrong. Alan
