Two years ago we made a hanging shelf on the terrace. It was intended for a cage with amadins.
In April, I noticed that pigeons like to sleep there. Then I did not attach any importance to this. But now I was going to put a cage there and ... oops ... It turned out that the pigeons not only made a nest there, but they were already waiting for the chicks ...
Of course, I did not bother them. But I think now I will have to wash the terrace very often ....
