Interesting, as always, Stewart.
I wonder if peregrines take many nighthawks. There are some birds that peregrines really get the best of, on a regular basis. Homing pigeons and Rock Pigeons both come to mind. Bufflehead seem to be taken frequently. Nighthawks are definitely agile in the air, perhaps too agile to be regular peregrine prey. On the other hand, their habit of flying about in wide open spaces might make them vulnerable.
I was just trying to think of alternative "limiting factors" besides nesting habitat and crows. Certainly, changes in abundance of flying insects might be another. Can you say Bt?
