Create a high home for Swifts

Set up a nest box to give summer-visiting swifts a place to nest and breed year after year.

Swifts come back to the same nest year after year. They like high, deep crevices for nesting, but the loss of many old buildings and the filling in and mending of roof spaces are shutting Swifts out of their favourite sites. 

Their numbers have declined dramatically and they’re now on the UK Red list of conservation concern. But you can help. Fix a wooden Swift nest box to the outside of your home to give them somewhere to nest. 

You can buy a ready-made box from our RSPB shop or if you fancy a bit of DIY, here’s how to make a Swift nest box.

Instructions

Where to put a Swift box

First you’ll need to check you have a suitable spot for your nest box. Place it on the wall of a building, ideally under the eaves (where the roof hangs over the walls). It should be 5m (15 feet) above the ground and easy for Swifts to fly into. Think of how a Swift will approach the nest – it flies down and then up to the nest site at speed, the upward swoop helps it slow down to land. The box shouldn't be in direct sunlight, so place it on a wall that faces north, east or somewhere in between. (Note: If you are having major renovation works done, you can use a special Swift brick. These fit into the fabric of the outer house wall. However, it should only be done by a qualified builder.)

Swift nestbox plans – make your own

Measure out the pieces of your exterior plywood according to our diagram. Cut all the pieces, including the rectangular hole into the front, shown in black, 28mm high and 65mm wide.

Note: the dimensions shown are for 12mm thick wood.If your wood is different to that the dimensions will need to adjust accordingly to match the size needed for the opening.
