I discovered the place where the blue tit made its nest. It’s just a crack in the trunk of an old apple tree. Such a small bird does not need much space. Interestingly, she raises a lot of offspring. How can she feed so many chicks? A very useful bird. Unfortunately, the population here is very small. In winter, when it is easier to observe tits at the feeders, the blue tit appears only occasionally.
Pay attention to the photos. He even has a newspaper to read in the crack. I tried to be discreet. I don’t know if the cats were there too, because the socket was 1 m above the ground.
