Swifts have declined by 53% between 1995 and 2016. The RSPB thinks loss of nest sites could be contributing.
If you’ve seen a nesting swift or screaming parties of swifts, the RSPB would like you to tell them to help build a picture of where swifts are nesting and where they need help.
You can find out how to do that here: RSPB Swift survey
It will also help you to identify swifts as they are sometimes confused with swallows or house martins.
From the 22nd – 30th of June Swift Awareness Week will be taking place.
