At the highest point of the farm is a water tower, a cube-shaped, steel-clad building containing water tanks. It is somewhat isolated, so not the normal setting for Swifts, but the building itself has boxed in eaves on the east and west sides which are plenty high enough and wide enough for Swift boxes. It also has mains power inside.
We are using this project as an experiment, giving Swifts a choice between boxes with 150mm headroom and 78mm headroom. A single-brick nest box would be 78mm high.
The 12 boxes are all basically the same, with entrances at the left or right end. As we could not decide whether to put entrances facing horizontally or vertically downwards, we used a compromise. The floor area of the boxes is 266mm x 200mm. All the odd-numbered boxes have a removable false ceiling.
We have previously set up experiments like this, including this one which has had some success.
