Today I went to one of the locations where I have nestboxes and checked all 22 of them. It was a successful day by my standards since I managed to ring 72 Great tit and Blue tit chicks. There are a few more boxes with baby birds that were way too little for ringing and I saw a Semicollared flycatcher nest in one of the boxes. So there is a potential for a few more ringed birds.
For the observation of those nests, I'm following strict rules, and people without experience and permission to monitor nests should avoid disturbing them.
