Two piece quirky bird box.
25mm diameter hole for smaller birds like Blue Tits.
The top section is screwed to whatever you're fixing it to (preferably the flat side of a building and out of the sun and wind), the bottom section slides into the grooves on the top section and is held in place by the tab clips.
