Swift Nest Box Schemes and Population Recovery

Common swifts have declined sharply in the UK due to loss of nesting cavities. Nest box installation is a direct welfare intervention.

Key Facts

Common swift populations have declined by approximately 50% in the UK since 1995
They nest almost exclusively in buildings, using cavities under eaves and in roof spaces
Modern construction methods and building renovation seal swift nesting sites
Swifts return to the same nest site every year for up to 20 years - losing a site is long-term loss
Nest box installation and nest brick incorporation in new buildings provide alternative sites
Swift calls played near new boxes can attract birds during their first return
RSPB and RSPCA campaigns have significantly raised awareness of swift nest provision

Welfare Considerations

Swift welfare is directly impacted by loss of nesting sites - birds returning after migration to find sealed nest sites must find alternatives or fail to breed. The welfare solution is practical and achievable: installing nest boxes and requiring swift bricks in new buildings near known swift colonies. Swift population recovery is primarily a housing and planning challenge, not a species biology challenge.

What You Can Do

Install swift nest boxes on suitable buildings before the February planning deadline
Advocate for swift brick requirements in local planning authority developments
Join your local swift group and report swift sightings to help identify colonies needing protection
Check roof and eave access before any building renovation from April to September
