I have here a wooden bird house for small to larger birds, the wood is treated and has been stained with Ronseal 5 year wood stain, so it will last, the measurement's are in the description above.

To hang the birdhouse there is a hole in the back, where the screw goes in to hold it in place, so all you have to do is to screw the screw into a post or fence that is provided, and fit the bird house  hole over the screw and pull it down, you can adjust the length of the screw so you get a snug fit.

Thank you for looking
