Very hard to say at this distance Uwe.
The dark bird must be a Brown Falcon as the tail is too short for Black Falcon.
The pale bird could be called a possible Grey Falcon but at this distance there is no yellow visible on the face or feet which would rule it out from BARC. The promising thing is that there is no black sub-terminal band across the retrices suggesting a juvenile Grey Falcon.
Exciting stuff mate. If you manage some more sightings this could be a ripper.
Cheers.
