How are the Swifts round by you this year?
I noted in my nature diary last year that they had returned on May 11th. This year I haven't seen or heard any. DH told me he'd seen some on his way to work last week, and someone in a local wildlife group said the Merlin app had picked up Swifts flying over a local park, but I'm quite worried by not seeing or hearing any at all yet.
