this is what i see.
White chin AND cheek (apologies Tim for my previous post, you were quite correct) with a distinct moustache - peregrine. HOWEVER the back of the head is pale grey (not dark grey as in a peregrine) the uppers are rusty brown - there is no large brown blob obscuring the bird. It is a mutant peregrine kestrel cross, bred by the CIA to confuse birdwatchers worldwide and give us something to talk about.
