mirror mirror on the wall

excellent idea, ive an old mirror i was wondering what to do with

I love using mirrors in the garden

This is a beautiful one, I am turning green :-)

Please tell me about the little box on the side of the shed.
Have birds used it?

I've thought of putting something similar on my shed, so any advice welcome, please.

The little blue one ?
Certainly looks like a bird-box, doesn't it?
I would be interested to hear of experiences from those whose boxes have been occupied too. I have had house martins nest below the eaves of the house, robins nest in plant pots stored just inside the greenhouse door and have found several empty nests in my beech and conifer hedges but have had little success with nesting boxes.
