Why are their breeding numbers plummeting?
We believe loss of nest sites is at least partly responsible. These migrant birds return from their wintering grounds in Africa to the same spot each year to breed – usually in buildings, in gaps under roof tiles and eaves.
Due to our tendency to seal up buildings during renovation or knock them down, swifts are returning to discover their nest site has gone or access is blocked.
