If Starlings are a problem then reduce the entrance to 28mm high
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.

Under the eaves is an ideal place for Swifts
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].
|Entrance made with cuts of 80mm by 30mm|
In both of these cases, the Swift can brace itself against the wall before entry.
|Entrance made with cuts 65mm by 45mm|
Both of these latter two ideas can be built without a back, provided the wall is not too uneven. The Swifts may get improved purchase on a rough wall.
