Swift bird boxes
To introduce our next unit, we will build swift bird boxes following this design we found for a really simple box.
From the website:
Buy a plank 180cm x 15cm x 15mm thick and cut it into pieces: (4 x 375mm, 2 x 120mm, 1 x 40mm). You should have a small bit left over. Then saw out the entrance from 1 of the long pieces (2cuts 80mm & 45mm resulting in an entrance 65mm x 30mm).
The material can be weather-proof ply or pine. In either case, the wood should be treated externally with a wood sealant.
Then assemble all of the pieces, except for the front, using nails, glue or screws. The front should be screwed on, without nails or glue, so that it can be removed for maintenance and for installation. Installation is by 2 screws through the back into the wall.
The canopy above the entrance is narrow with a sloping top. It provides some shelter (as well as ‘decoration’), but it does not allow predators to perch on it.
This box should not be put anywhere where the rain or sun can fall upon it, so it is only appropriate under horizontal eaves, which are at least 200mm wide.
[Hint, when you make the entrance, aim on the small side, you can always take a file to the edges to make it a little larger. If you make it too large, Starlings will get in].
