This time of year in my neck of the woods, Starlings gather in numbers for the winter and form swooping 'clouds' as they flock together ready to roost for the night.
Had to pull over on the way home to watch a spectacular performance by a large flock (I'm guessing 50,000 or so birds). Didn't think to get the camera out (bugger), but here's a clip of the phenomenon that always has me mesmerised.
Starlings on Otmoor
Cool or what?
ETA - another good clip
