Swift Conservation in Urban Areas: Welfare and Housing Solutions

Practical welfare and conservation guide for swifts in urban environments — nest site provision and protection.

Key Facts

Common swifts spend nearly their entire lives airborne except when breeding
Urban swift populations have declined as modern building renovations block access to nest cavities
Swifts are site-faithful — they return to the same nest site year after year
Loss of nest sites causes breeding failure and colony abandonment — a direct welfare harm
Swift bricks — specially designed hollow building components — provide permanent nest sites
Swift boxes can be retrofitted to existing buildings as an alternative to swift bricks
Call-lure systems (playing swift calls during the breeding season) can attract new colony establishment
Planning requirements for swift nest provisions are being adopted by several local authorities

Welfare Significance

Urban swifts face a welfare crisis driven by the loss of nest sites through building modernisation. These remarkable birds, which evolved to nest in tight crevices, cannot adapt quickly to the loss of their ancestral sites. Providing swift bricks and boxes in new and renovated buildings is a simple, low-cost welfare intervention with significant population-level impacts.

What You Can Do

Install swift boxes or bricks on your home or building
Use a call-lure system during April-July to attract swifts to new boxes
Advocate for swift provision requirements in local planning policy
Check for active swift nests before any building renovation work
