diamond dove baby question

[tinysparrow]

Does anyone know when diamond dove babies will begin to display if they are males? My diamonds had their first baby ever and it is about two months old now. I noticed today that the baby has begun practicing its vocalizations, (which was really cute as each time the baby would do a little "coo" it would move its tail up and down!), and I was just wondering about what age I can expect to see it displaying if it is a male. Any help would be appreciated.

Thanks!
