Doves are supposed to be the representatives of peace. From what I know about them, they don't build very sturdy nests and they are very tasty when breasted, wrapped in bacon, and baked or bbq'ed.
Last year a pair of doves made a flimsy nest in my little wisteria covered pergola. They ended up raising at least three clutches, something I didn't know they could do. This year they are back.
