Same here! We're up to 21 (there's probably more hiding) in the bushes at the back of their garden. with the other encouraging posts I've seen on this forum hopefully this means they're making a comeback.
I usually get a small party for the BGBW but they didn't show this year. That could be because the bush they usually visit had been pruned or I had changed the time of day. How do you count those large numbers? I start to to lose track with 4 or 5 dodging around and going behind branches.
