I recently put a hanging basket with a leafy plant on my balcony. A few mornings ago, I noticed that a couple of birds were perched in it, so I took the basket down and took out the nest they were building and put it back after a few days. This morning, I found them rebuilding the nest and my dad pointed out that they were doves. He said that it should be ok because they are very peaceful animals and they won't get defensive of their nest, regardless of whether or not they have younglings. Is this true? I like the idea of having some doves nesting on my balcony, but not if they'll be defensive. Could anyone help me out? (no offense, but please only answer if you know what you're talking about.)

Oh, and if it helps, I think these are mourning doves. I just can't seem to find anything about their nesting habits. Thank you!
Unfortunately, I had already moved the basket before I found out it was illegal, reason being that the basket was right in the middle of my balcony and would have disturbed the birds more, I think. (It's a pretty small balcony, maybe 15'x15') I moved it to the outside and I saw them there this morning "looking" for the nest. They may not come back, which would probably be better for them so that they won't be disturbed. Still, it would be cool if they did come back. *sigh*
