thanks, bigfrank.
i saw it fly away at 4:40 PM. before it flew, i saw it turn and it spread its wings and it definitely was a falcon.
when it flew, there was a lot of rapid wing flaps. i saw it circle around and head northwest and disappear.
it wasn't a huge bird - i'd dare to say it was smaller than a merlin and bigger than a pigeon.
i was hoping to see it hunt, but oh well.
also of note - saw a turkey vulture fly over the water tower while the falcon was sitting there.
