UK swift (bird) numbers - NOT amateur radio

 According to conventional wisdom, the numbers of swifts should be down as there are fewer nest sites. Certainly around here in East Anglia we have seen far fewer swallows, although I have seen them elsewhere.

As far as I can tell, there are more swifts than last year here. This is a good sign and others have noticed this too locally.  Maybe they are adapting and finding new places to nest.  I really hope so. Some are erecting swift nestboxes or "swift bricks" to encourage them.

I would be interested to know what others in the UK are finding. Swifts screaming in feeding parties signify summer in England. They only come here for a few months to breed.
