Swifts (birds)

My (very unscientific!) view is that there are at least as many swifts about as last year. If anything there are a few more. 

I judge numbers by the number I see in the sky. It has been rare to look up and not see swifts.

People expected numbers to be down as there are fewer nest sites.

They only stay in the UK  for a few months. I hope to see them next May.  They are still here at the moment, but one day we'll look up and realise they have gone.
