Swifts in Crisis: A Call to Action for Britain's Summer Birds
Swifts are the ultimate endurance athletes of the sky, wheeling and screaming through British summers. These remarkable birds spend up to nine months airborne, flying approximately 14,000 miles annually on migrations between sub-Saharan Africa and the UK. Their arrival heralds the warmth of summer, while their departure marks its end, offering breathtaking aerial displays that captivate nature lovers. "Swifts spark joy," declares Hannah Bourne-Taylor, a swift advocate and author. Edward Mayer, founder of Swift Conservation, recalls childhood moments watching them, describing them as "absolutely gorgeous ... like an aerial shark, in perpetual motion."
Why Swifts Need Urgent Help
Despite their beauty, swifts face a severe decline. From 1995 to 2023, the UK swift population dropped by 68%, a consistent trend across the country, according to Dr Guy Anderson of the RSPB. The loss of nesting sites is a key factor, as modern building practices seal off the nooks and crannies swifts rely on. However, insect decline poses another major threat. Swifts feed exclusively on insects, and research links poor weather events to reduced breeding success, with climate change increasing such volatility.
10 Ways to Support Swift Conservation
- Become a Nest Detective: Use the RSPB Swift Mapper app to record sightings of nesting swifts or their "screaming parties." This citizen science tool helps conservationists target efforts effectively.
- Champion Swift Bricks: Advocate for mandatory swift bricks in new builds. These small structures provide permanent nests and are easy to install during construction or renovations.
- Install Swift Boxes: Place nest boxes under eaves at least five metres high, with a clear flightpath. Swift Conservation offers templates and advice for DIY installation.
- Be Patient and Welcome Other Birds: If house sparrows or other species use your boxes, that's beneficial. Swifts may evict them later, and it supports other at-risk birds.
- Broadcast Swift Sounds: Play recordings of swift calls in June and July to attract prospecting young birds, available from Swift Conservation.
- Protect Insects: Create wildlife-friendly gardens with flowering plants to boost insect populations, essential for swift survival.
- Get Involved Locally: Join swift groups through the Swift Local Network or participate in Swift Awareness Week for community actions.
- Engage in Citizen Science: Contribute to surveys like the Breeding Bird Survey to enhance conservation knowledge.
- Help Grounded Birds: For juveniles, contact a swift carer; for adults, gently bounce them on your hand to encourage flight, but never throw them.
- Enjoy and Inspire: Appreciate the short swift season and let it motivate efforts to protect these incredible birds.
By taking these steps, individuals can make a tangible difference. As Bourne-Taylor notes, providing a nest is "the only ground they will ever intentionally touch in their whole lifetime. What an investment!" With collective action, we can help reverse the decline and ensure swifts continue to grace our skies for generations.
