Swift Decline: UK's Swift Population Drops by 68% in 28 Years

AI Summary
The UK's swift population has declined by 68% over the past 28 years, from 1995 to 2023. Conservation efforts are underway to protect these birds, including the installation of swift bricks and nest boxes, and the use of citizen science projects to track their populations.

The UK's swift population has been declining at an alarming rate, with a 68% decline recorded between 1995 and 2023. This has led to a significant decrease in the number of swifts in the country's skies, with many conservationists working to protect these birds.

Swifts are known for their impressive endurance, flying 14,000 miles annually from sub-Saharan Africa to nest in the UK and back again. They are a beloved species, providing a heart-soaring display of beauty with their long swooping wings and pale throats.

Why do they need to be saved?

The reasons for the decline are complex, but it's likely that the loss of nesting sites is a contributing factor. Changes in building management and renovation practices over the past 100 years have made it harder for swifts to find the holes and nooks they need to nest. Additionally, insect populations are believed to have declined, which can impact the swifts' food supply.

How can you help?

There are several ways to help protect swifts, including:

  • Become a nest detective: Use the RSPB Swift Mapper app and website to record sightings of nesting swifts and help conservation groups focus their efforts.
  • Install swift bricks: Fit small structures into building walls to provide a forever nest for swifts.
  • Install swift boxes: Build or purchase inexpensive nest boxes and install them under eaves at a minimum of five meters high.
  • Protect insects: Plant flowers, nectar, fruit, and berries to support insect life and bird life.
  • Get involved in local swift conservation: Contact a swift group or local RSPB group to get involved in conservation efforts.

By taking these steps, individuals can help make a difference in the conservation of swifts and protect these amazing birds for future generations.
