Garden warblers

Having not been up in couple of weeks, I went to check and see if the garden warblers were here yet. And I was amazed to count 8 separately distinguishable individuals in one relatively small area of the Pennine way / eastern side of Jumble Hole. They were almost certainly 4 pairs, with 4 singing males seemingly accompanied by 4 'chacking' birds close by.
No whitethroat as yet, but I haven't ventured far in truth.
