Bluebird babies in my backyard house are almost ready to fledge. They are thirteen days old today. Usually on day 16-18 they will leave the nest. I always get nervous hoping they all make it out and survive the five foot flight out of the house. The Mom and Dad Bluebirds are feeding and taking good care of them and will continue for weeks after they fledge but I still get nervous. It has been a joy to watch these babies hatch and grow every day. I cannot open the door any more as you can see they may fly away too early. So I sit back and wait now for their first flight. You can see it is a little crowded in the house as they grow each day.
