City Falcon Is Nobbling "Rarities

I was inspired to do this sketch, after hearing about the Peregrine hunting at night under the guise of the bright lights in both the illuminated City of Bath and also at Aylesbury.
It came as a suprise to see that "rarities" like Corncrake, Leaches Petrol, etc etc had been passing through the City and overland and hence had been its prey, with lots of evidence of leftover wings and the like to be later found under its nest sites and later analized.
