Common Swift Welfare and Urban Conservation

Common swifts are highly specialised aerial birds that spend most of their lives in flight, with urban nesting site loss being the primary welfare and conservation challenge in the UK.

Key Facts

Swifts cannot take off from the ground — nesting site loss is essentially a death sentence for displaced birds
UK swift populations have declined by 53% since 1995 primarily from loss of old building nesting voids
Swift nest cups and swift bricks can replace lost natural nest sites in building renovations
Swifts return to the same nest sites year after year, making site protection particularly important

Welfare Considerations

Swift welfare is inseparable from nesting site availability: a swift without a nest site cannot successfully breed and loses a critical component of its life. Building renovations that seal old buildings' eaves and gaps eliminate nesting opportunities that swifts have used for generations. Swift-friendly building regulations requiring either retention of existing nest sites or provision of equivalent replacement features protect swift welfare at a structural policy level. Individual swift brick installation in new and renovated buildings creates legacy nesting infrastructure that will be used for decades.

What You Can Do

Install swift nest cups or bricks if undertaking building renovation or construction
Advocate for planning conditions requiring swift-friendly features in new buildings
Report swift colonies before any building work to ensure they are protected
Support local swift group surveys and nest site mapping in your area
