Just in case anyone is interested in getting some Swift nest boxes up, I’ve stolen the text below from Robert Kelsh,
Andy.
…I had v rapid success with two when I lived in Westwood - they were inspected by local juveniles in the autumn and then occupied the next year!
Design is v simple: c. 12W x 6H x 6D inches with a small (1.25 x 3 inch) hole at the bottom as an entrance. Box should be painted white to limit overheating, with entrance in a position away from prevailing wind/rain. Also should be on a high wall with a long clear view for them to drop out of and gain speed (to gain lift) - under eaves of a standard two story house, facing out over quiet residential road worked well for us.
…there is a short piece in this month’s BB - and it includes a photo of an 'alternative' design (actually v similar to the one I outlined).
...but be patient, or use a tape to attract potential nesters to the area of the nest box…
