Swift Colony Conservation and Box Installation for Welfare

Common swifts have declined by over 50% in the UK as nest sites disappear with building renovation, and installing swift boxes in new or renovated buildings provides direct welfare benefit to this charismatic migrant.

Key Facts

UK swift population declined 53% between 1995 and 2018
Swifts nest almost exclusively in human buildings in the UK
Modern building techniques eliminate traditional nest sites under eaves
Swift boxes provide 40 years of use once established by a colony
Swifts spend 10 months of the year in the air, only landing to breed
A single swift pair may rear 2-3 young per year with 5-year fledgling maturity

Welfare Considerations

Loss of nesting sites causes failed breeding attempts as pairs return to find lost access points blocked. Nest site competition and loss cause significant stress during the brief breeding season. Installation of swift bricks and boxes directly provides welfare-positive habitat. Swifts are highly site-faithful, returning to the same nest sites year after year, making each lost site a multi-year welfare impact.
