Alien tweet

That is to say a second hand tweet from a correspondent in Stoneleigh. Some kind of raptor being seen off by some crows. Raptor left, most intrepid of the crows right.

Augmented snap

With the original snap zoomed in Photos and augmented in Powerpoint with snaps turned up by Bing. A Microsoft flavoured effort. No checking with RSPB or anyone like that.

My vote is for sparrow hawk. Wings not the right shape for a kestrel. Too small for a buzzard. No forked tail so not a kite.

I shall consult a proper tweeter for his verdict.
