Swifts inside PVC soffits

Open eaves, with breeding Swifts, are frequently turned into closed eaves with PVC soffits. This is an example of such a project in Cambridge in 2020.

The pictures below show 5 neat holes in the Soffit of Gray House, a block of flats in Cambridge. Holes 1, 3 and 5 have an S Brick eaves box above them which contain any birds that enter these holes and they act as a barrier for any birds that might enter holes 2 and 4. There is a total of 8 S Brick eaves boxes in this building with 10 spaces for swifts.
