I like Pigeons and don't mind them except when they visit my balcony at 7am in the morning and wake me up (we only have single pane windows and no way to change it since we're renting).

Don't be sad on my account. I actually like them very much. They are funny and persistent. I watched one yesterday try to outsmart a crow for a piece of cheese. That she even tried was pretty courageous. We have an obviously-paired couple living on the roof of the building next door. They are very sweet and would be welcome to visit if they would promise not to nest. But they won't.

And the first pair of baby pigeons we sheltered was the last pair of baby pigeons we will be sheltering. The mess was indescribable and everyone was so comfortable they all wanted to raise families here. Horrified, I chased pigeons from our balcony during mating season (circa any time it's warm outside) multiple times a day for three years before I regained control of my tiny kingdom.

Pigeons have the whole outdoors to nest in, the city even maintains a pigeon house on top of a building just across the way. I have my balcony...
