Wildlife Swift Nest Protection and Conservation

Common swifts depend on buildings for nesting and are in severe decline, with simple nest protection and swift brick installation during renovation providing significant welfare and conservation benefits.

Key Facts

UK swift populations have declined by 58% since 1995, primarily due to loss of nesting access in renovated buildings
Swifts return to the same nest site year after year and are disrupted by renovation blocking access holes
Swift nest cups and swift bricks can be installed in new and renovated buildings to replace lost nesting sites
Legal protection of active swift nests in many countries means disturbing them during the breeding season is illegal
Swifts are long-lived birds taking 3-4 years to mature, meaning population declines take years to manifest and recover
Swift nest recording by volunteers helps identify important colonies and influence planning decisions

Welfare Considerations

Swift decline is directly attributable to human building renovation practices that unintentionally remove nesting access. Unlike many wildlife declines, this one has a simple and affordable solution in swift brick installation. Individual swifts that lose nest sites they have used for years experience significant welfare impacts from being unable to breed in a familiar, successful location. Population-level declines represent a conservation emergency with welfare implications for the species as a whole. Planning policies requiring swift brick installation in new and renovated buildings would transform this situation.

What You Can Do

Install swift bricks or nest cups on your property if you have south-facing eaves at height
Check your building for swift activity before any renovation and delay work until August when swifts have left
Advocate for planning policies requiring swift-friendly building design in your local authority
Donate to RSPB, Swift Conservation, and similar organizations working on swift population recovery
Register your local swift colony with Swift Mapper to contribute to national population monitoring
