Great news, Philly Blues – nothing better than to see a nest of bluebirds that you have catered to, fed, worried about and helped in any way possible, become empty knowing they have fledged into this big world. If you have been feeding parents you should see them bring the young ones back in about 8 or 10 days, after they have had them out learning how to hunt and to fly better. My 2nd nesters should be hatching in about a week – will have to contend with the heat this coming week and maybe put on my heat shield.
