Has anyone confirmed they were Starlings ? a previous poster has suggested Seagulls from a tip on final. Certainly the damage potential from an individual bird would be greater with the gull but Starlings possibly tip the balance by sheer weight of numbers.
There is a really nice big flock of Starlings whose favourite hang-out seems to be in the big tree at the far side of the carpark in front of the terminal in GRO. I have already "suffered" at their hands (or asses in fact
) whilst passing there, be careful at dawn & dusk guys, there are hundreds if not more in some of these flocks I have witnessed.
