Pigeons defy Bethesda 'hawk'

This hawk is a pretty poor deterrent to these pigeons, who seem quite content to share a perch with it.
The hawk (which is made in stone of course) was placed on the historic Bethesda Chapel in Hanley to frighten away the pesky pigeons - who nearly ruined the chapel during the time it lay derelict. (It's been much restored and saved, over the last few years).

I think the chapel's supporters may need to use another system.
