Overnight guest gone

A photo from a few weeks ago. According to the poo it left, it stayed around for about 3-4 nights. Have not seen it yet, hope it's doing fine. The other balcony locals are there, and i am going to have new pigeon babies on my balcony in a week, Martha and her partner are sitting on eggs 🙄 I've checked the eggs but they are a few days too far in development for my ethical compass to still swap them for fakes. Very well hidden.
