More swifts? - NOT amateur radio

There are certainly fewer swallows. At one time there were masses on telegraph wires. To see a swallow at all these days is a rare event here. 

The common view is that swifts are in decline too. That is not my experience. Although this may be local, I have found more swifts this summer than the last few years. Last summer I could look skywards and wait 30 minutes to see a swift. This summer, I look up and almost immediately see a swift. It would be good to know the experience of others in the UK. 

Certainly, many swift nest sites have gone. Have they adapted? It would be good if this was true.
