I think, the pale head is at least partly due to lightning, head in sunlight, rest of the bird in shadow.
While a catiuos approach is often better, BOTH pictures shows a typical Hobby to me with long slender, swift-like wings in relation to body.
And I think I can see the right red colour on the trousers. Or is this wishful thinking?
Thank you for the comments! Do you think there is any chance to be Falco eleonorae (Eleonora's falcon)?
My abiding memory of Eleanora's Falcon adjacent to Mount Olympus Greece many years ago, was of an extremely long-winged and tailed Falcon, giving an extremely ''rakish'' look, quite unlike your images. :t:
Cheers
Long tail is good for RFF, but I think the body is not striped, which is good for a mâle RFF (2 cy ?). The head is not white IMO, it is just due a strong light, rather on a dark area that is making more often this "flash" effect than pale areas.
But for me this bird looks like an IDable Hobby, wings on Rff look broader and not so swiftlike in my experience.
Sorry about lightning, I hope as a non native speaker, my english is as not as bad as my photos.
