So I have two doves, perviously I thought my brown one was a boy and the white one a girl, the brown one has been cooing and sticking his butt up in the air and rapidly flicking his wingtips trying to get the attention of the white dove, What really confused me was today the white one started cooing back. The brown dove also constantly sits and coos in the nest box I built for them and this morning "he" started breathing a bit heavily and shaking, almost vibrating, could "he" be getting ready to lay eggs?
