Swifts have graced the skies of Lewes for generations, filling summer evenings with their joyful screeches and breathtaking aerial displays. But these remarkable birds are in trouble—Swift numbers have plummeted by 58% since 1995, and they are now on the red list of conservation concern.
That’s where Lewes Swift Supporters come in. This passionate community group, led by dedicated volunteers, is determined to protect and expand the town’s Swift population. By monitoring and safeguarding existing nest sites, creating new homes, and spreading the word about these extraordinary summer visitors, they are ensuring that Swifts remain a part of Lewes for generations to come.
A Town That Welcomes Swifts
Lewes has long been a stronghold for Swifts, with an estimated 10% of Sussex’s Swifts nesting here. However, modern building renovations and construction methods have removed many of the nooks and eaves where Swifts once built their nests. In response, Lewes Swift Supporters proposed a bold step: making Lewes a Swift-friendly town. In September 2024, Lewes Town Council formally approved this initiative, marking a collective commitment to raising awareness and taking action to support Swifts.
Action in the Air
Each year, from late April to early August, Lewes Swift Supporters conduct systematic surveys to identify active nest sites and areas where young Swifts are searching for new homes. This information helps pinpoint Swift "hot spots" where additional nest boxes can make the biggest impact. The group also provides guidance to residents who want to install their own nest boxes, empowering the whole community to be part of the solution.
But their work doesn’t stop there. Through Swift walks, talks, and collaborations with local councils, they advocate for the inclusion of Swift bricks in new developments and renovations. They also host the annual Swift Watch, encouraging residents to report sightings and celebrate the birds’ return each summer. The group also encourages local people to get involved in actions that support a Swift Friendly Town, including planting native trees and wildflowers, digging ponds, building bug hotels, and leaving areas of dead wood in gardens and other spaces.
The Bigger Picture: Biodiversity and Swifts
Swifts are a sign of a thriving ecosystem. They feed on insects, consuming up to 20,000 a day to nourish themselves and their chicks. However, insect populations have dropped by 61% since 2004, making it even harder for Swifts to survive. By supporting Swifts, Lewes Swift Supporters are also championing broader biodiversity efforts—working alongside groups like Lewes Climate Hub, Wildflower Lewes, and The Railway Land Wildlife Trust to create richer habitats for all wildlife.
A Movement for Everyone
Lewes Swift Supporters believe that saving Swifts is something everyone can be part of. Membership is free—anyone can join, receive updates, and get involved in hands-on conservation. Whether by installing a nest box, joining a Swift survey, or simply looking up and marvelling at these incredible birds, every action counts.
Together, this community is proving that small efforts add up to big change. By protecting Swifts, they are not just saving a species—they are strengthening the bond between people and the wild, ensuring that the skies of Lewes remain filled with the magic of Swifts for years to come.
