Perhaps I am missing something (don't think so), but this looks like a female Peregrine to me. The strength of the head pattern, overall proportions, width of the wings, and fast cadence of the wingbeats all suggest Peregrine to me, albeit a bulky one.

In Peregrine Falcons, the Primary 9 (P9) is the longest, P8 is usually
second longest and P10 is next. The gives the impression of a very
pointed wing. The feather are also usually the same tone as the coverts
giving the impression of a uniformly dark underwing.

In Gyrfalcons, P9 is longest, but P8 and P7 are nearly as long and P6 is
also longer than P10. The attachment positions of P7 and P6 in the wing
obscure their actual lengths relative to P10, but contribute to the
impression that Gyrfalcons have a more blunt looking wing.

Lee's bird appears to have a wing formula consistent with Gyrfalcon,
though I agree the head pattern is equivocal.

I will be out tomorrow roaming the dog infested wilds of the Youngs Bay
Dike looking to score photos of a greater resolution...
