Swifts are now arriving back in the UK and need somewhere to nest. Suitable sites for nesting are disappearing all the time, as old buildings are demolished or refurbished.
We realised that the workshop at our Cambourne office was a great place to put up some nest boxes and try to encourage some swifts to a new site. There is a high wall that allowed us to install the boxes above 4.5m - an essential requirement for swifts. The position will also allow fledging birds to fly away clearly, without hitting trees or overhead wires.
Our building didn't have any eaves, so we chose a sloping-roofed design that can potentially be installed on any building. In this case we used the Model 30 design from the excellent Action for Swifts website. You can see from the photo that this box has a circular wooden nest form inside - this structure gives the swifts a headstart when they start to build a nest.
