Could you provide their scientific name (or just a wikipedia link) to your raptors identification? They look a lot like kestrels, but not quite eurasian kestrels.
Just curious.
" Other recent DNA analysis takes a similar view that the American kestrel is not a true kestrel, but rather than being linked to the hobbies is more likely genetically more closely related to the larger American falcons such as the peregrine falcon,[2]" en.wikipedia.org/wiki/Kestrel
