Five, possibly six, little ones flew out of the Carolina Wren nest in the porch mailbox ths morning. They all made it safely to a big tree. One, however, landed on the trunk of the tree and promptly walked up the trunk to the leafy part much like a Brown Creeper.The whole event was exciting!! Didn't see the Bluebirds exit their box but I think they, too, have flown. Nita Laughlin Springfield, TN 5/22/13
