That was quick!

This is the nesting box that has been in our garden for years with absolutely no interest from any bird of any description. 
A few days ago, as mentioned in a recent blip, I put that bit over the large square hole and drilled a 25mm hole in it.
After the makeover I put it back on the market and already getting some viewings!

Today I opened my blind to the sight of a blue tit showing great interest as it perched on the hole (extra photo). It then popped in and had a look to see what the view from the 'Window' was like.
Keeping a very sharp eye on the box to see where this leads.

Not great photographs but it was taken through a double glazed bedroom window.
