In just 20 years, more than half of our swifts have vanished and we believe that the loss of nest sites in the roofs of buildings is at least partly responsible. By using Swift Mapper, you’ll help locate breeding hotspots for swifts and protect their homes.
Go to Swift Mapper
Swifts pair for life and meet up at the same nest site in the UK each spring – usually in gaps under roof tiles and in the eaves of buildings. But as more and more old buildings are demolished or renovated, many swifts are returning to discover their nest site is gone.
By telling us where you see nesting swifts you’ll help to build a picture of where swift nest sites need to be protected and where it would be best to provide new nest sites.
How to get involved
We’d like to know where you’ve seen groups of screaming swifts or swift nest sites anywhere in the UK. Please follow all current government guidelines on movement and social distancing that are applicable to whichever part of the UK you are in, when using Swift Mapper.
If you’ve sent in records before, thank you. Please tell us what’s happening again this year – even if swifts are absent from nest sites they used previously – as it’s important to know if breeding colonies are stable.
What to look for
Watch out for groups of swifts flying fast at roof height, often screaming loudly – this means they’re breeding nearby. Swifts nest in holes, so we’d also like to know if you see swifts entering holes in buildings.
Please don’t report swifts flying high in the sky, feeding over water or fields, or away from settlements on Swift Mapper. These birds could have travelled long distances and may not be local breeding birds. Please use BirdTrack instead, if you would like to record these sightings.
Give swifts a home
With our specially designed nest box you can provide a safe and much-need place for swifts to set up home.
