Some encouraging signs John.
We're getting there slowly Roy.
I've seen nesting material being gathered by crows, and blue tits picking out spiders webs from crevices on the wall
SDT: The only other I have seen so far has been a Starling.
it looks like a woman's work is never done!
TWG: So they tell me ;)
Thank you for visiting. Hope you enjoyed the pictures. Any comment, or correction to any information or identification I get wrong, is most welcome. John
