Swifts - NOT amateur radio

These are migratory birds that are supposed to be declining in numbers mainly as result of fewer nest sites. 

We certainly see far fewer swallows although I saw plenty in Devon last week.

This year, I seem to have spotted more swifts than last year. If I had not heard of the issue of falling numbers I would not have known. Maybe locally there are still plenty of swift nest sites or numbers are growing again? For example, there were about 20 screaming overhead earlier in a feeding party.
