And here are some swifts from Dubrovnik last week. That dark shadow at the top of the frame is the edge of the awning at the outdoor restaurant where we sat, at the water's edge just outside the medieval city walls. Around sunset the Alpine Swifts came swarming out from those walls and I got a couple of shots of the masses of them, just by pointing the camera into the sky and snapping. I think there are about 50 in the frame. You can tell they're Alpines, even at this distance, by the oblong patch of white on their bellies (those that happen to have their belly turned towards the camera), framed in by dark head, wings and tail. I'm pretty sure I saw Pallid Swifts earlier in the day the next day - uniformly grey underneath, but for a lighter patch at the throat - but I didn't get a shot of any of those.
