as i was shooting the Cattle Egrets, i saw ibis, dowitchers and yellowlegs in the pond, then all of a sudden something biggish flew over and cleared everything, even chased the great white egrets, it was blackish on the back, smaller than the Harrier but bigger than a Kestrel, he was moving too.
I spotted something across two ponds, not a great pic but it id's my raptor as a Peregrine Falcon.
