Agree its a great bird. If the observer wanted to they could have put the site out, as I see it by not doing so they would probably not appreciate birders peering into gardens. And back to my original post pointless unless there is some one-upmanship going on in the area?

Given the tendency of wintering phylloscs to frequent waterways there must be a good chance that its more likely to be seen along the towpath than in any garden?
