Defensive

Driving along the Broad Haven road towards H'west last night (18:30) I saw ahead of me what looked like a fairly large Starling flock performing with the defensive flying routine, but there was something a a bit odd about it, the flock looked to far away and so the birds looked too big, sure enough, by the time I had reached Ruther park, I could see that it was a very large flock of Jackdaws with what was surely a peregrine in attendance, but that's more of a guess.

Early morning travelers through this stretch may well have observed the large resident flock of Rooks and Jackdaws that gather here at such times.

The whole flock were behaving in exactly the same manner as the Starlings do in the same circumstances, and while I have seen it many times with them, I have never seen a flock of Corvids behaving in this manner, anyone else?
