Swift Colony Conservation in Urban Areas

Swift populations have declined steeply due to loss of nest sites; conservation action in urban areas is critical for recovery.

Key Facts

UK swift populations declined by over 50% between 1995 and 2020
Swifts nest almost exclusively in buildings and are legally protected
Renovation and demolition destroy nest sites faster than new ones are created
Swift boxes and specially designed bricks provide new nest sites
Swifts are highly site-faithful and return to the same nest site each year

Welfare Considerations

Swift population decline reflects the loss of nesting opportunities that these birds depend on absolutely. Swifts that return to find their nest sites destroyed face reproductive failure and must search for new sites while in poor body condition after long migrations. Proactive nest site provision addresses a clear welfare need at population scale.

What You Can Do

Install swift nest boxes on your home or building
Advocate for swift bricks in new building regulations
Join your local swift group and participate in colony monitoring
