Question Author
Hmmm, interesting, I live in a town of about 8,000 just outside Edinburgh and while there is plenty of farm land and open land around, just where I live it is like something out of 'The Birds', would it be possible that they come in to feed as I dont see any evidence of nests in the taller trees?
Actually, have just been in the back garden and there is not one to be seen which is extremely weird!
There are two distinct sizes of these birds - large and small - so are they all rooks (as they are in flock) and some are mature and some are young?
Apologies for more quesitons!
thanks
