In Switzerland, Common Swifts and Alpine Swifts primarily nest in buildings, finding crevices to settle in. The destruction of old buildings and renovation works cause countless nesting sites to disappear each year. Swifts are very loyal to their nests and struggle to find places to nest.
The Swiss Ornithological Institute compiles and provides information for owners, architects, municipal authorities and other partners on measures and possible arrangements for the benefit of swifts.
