It's DEAD.

       Imagine the work entailed. Can't vouch for weight, but at least 5-6 volumes of a single Bluetit for single use
      Jerra being a useful young fellow ;¬ )  went up the Wall (Metaphorically & literally) to muck out my Blue Tit's Nest Box.
       The dead nest; and spider; which I didn't notice until later are now awaiting the recycling Wagon's visit.
