Bluebird Progress Day # 1 Day # 5 Day # 10 Day # 15 Day # 17 The Bluebirds fledged this morning before I checked the box. As you can see the box is a mess and in great need of a clean out before the next clutch. The adults keep the nest free of fecal matter up until a few days before the fledge. This helps to convince the young to find a better place to roost. If things go well momma will be back in a few days and begin building nest # 2 for her 2nd clutch of this year.
