On a pub crawl round Bolton on Thurs, around 100 still in the same tree. My companion asked if they were nesting up there.

100+ PW's in same tree outside Cafe Nero at 10pm last night. Great Sight.

4.30pm 150 pied wagtails in usual tree outside Cafe Nero. Surprisingly there are three trees close together, but all the birds were in one tree, quite a sight!
