Well, here is an interesting piece.
Somewhat akin to practicing scales on the piano, whenever I am walking about with Nikon in hand, I try to quickly follow and focus on any flying object that crosses overhead, just to see if I can do it. I don’t know the difference between crows and ravens (and googling hasn’t really helped me clear up the distinction), but whatever we have here, we have a bunch of them. Like these from the other day.
