To continue the Murmuration discussion,
I can definitely see how that could happen! They are incredible to watch and the sound when they’re right overhead is insane but yeh… awful lot to have them all getting food from the feeders. This is near the farm and thankfully they stick mainly to the Moor so I’m incredibly lucky, I get to see the displays and don’t have to deal with the clear up! 
That’s such a shame though again, yes, if you lived in the buildings I can understand the problem. Pity from the gig goers pre gig entertainment perspective though.
