 Our Challenge 

The Common Swift (Apus apus) Vanishing from Our Summer Skies

 

Every May, Swifts return from Africa to the same rooftops where they were born. For centuries they have nested in the cracks and eaves of our buildings. But modern renovations and construction are sealing these spaces — and many Swifts now return to find their homes gone.
Across Derbyshire and the UK, their numbers are falling.

 A Bird Like 
 No Other 

Swifts are one of the true sounds of a British summer. Their high-pitched screams and sweeping flight instantly signalling the season has arrived. What makes them special is how close they live to us, nesting in our buildings and bringing moments of wild nature right into our everyday lives.

They’re not just a joy to watch—they’re hard workers too. Swifts spend their days racing through the sky, eating thousands of insects and helping keep ecosystems in balance. And their lives are nothing short of extraordinary: flying almost constantly, travelling thousands of miles between Africa and the UK each year.

Put simply, swifts make our summers feel alive. Without them, something important would be missing.

 Our Swifts Are 
 In Trouble 

Breeding numbers of Common Swift Apus apus have declined across the UK by over 60% over the last 25 years.
Steep declines have been observed across England, Scotland and Wales since 1995, and we're still not entirely sure what's causing them.

The species has been on the UK Red List of Birds of Conservation Concern since 2021.

Loss of Swifts is part of a wider decline in our summer bird visitors, including Nightingales and House Martins.
Swifts have adapted to nest almost exclusively in buildings—especially older or abandoned ones.
A major factor in Swift decline is loss of nesting sites through building renovation and repair.

 A Local Issue 

There's still a lot to discover about the current state of nesting sites in Derbyshire, but key Swift "hot-spots" have been identified across the county.

Derbyshire Swift Conservation have identified key populations in Rowsley, Youlgreave, and Darley Dale in 2025 surveys.

But many nest sites are undocumented and unprotected—we need more help to identify and map Swift activity across the county. This county-wide approach is what makes Derbyshire Swift Conservation unique.

 There Is Hope 

With our help and research, Swift nesting populations can recover. While we don't fully know why Swifts numbers are declining, there are some actions we can take that are proven to help—and this a key reason why Derbyshire Swift Conservation was founded.

We can protect existing nest sites.

We can install Swift nest boxes on existing buildings.

We can include Swift bricks in new developments.

We can map and monitor local colonies.

We can engage communities and raise awareness.

We can work with local businesses to mitigate risks to nests.

And while we're doing all that, Derbyshire Dales Swift Project continues to investigate ways to better survey and conserve Swift populations.

 We're Not Alone 

We're of course not alone in our mission—there are a great many number of organisations and networks across the UK and Europe doing amazing work, and we'd not be doing our part if we weren't shouting them out. Here's to them!

  • Sheffield Swift Network
    Leads the way in employing Swift bricks, and has done great work in the creation of their Swift Streets initiative

  • Swifts Local Network
    An incredible resource that coordinates knowledge and allows individuals to share learning across groups


  • RSPB
    A nationally respected body that has created survey method guidance specifically for Swifts


  • British Trust for Ornithology (BTO)
    The definitive source of statistics on Swift population trends, and has identified dramatic declines of migrant species of birds
