My friend, Jeff Garvey [recforthebirds on Facebook] invited me out to an abandoned schoolhouse near Arapahoe, N.C. Jeff reclaims old buildings slated for demolition, and repurposes the wood and materials to make absolutely delightful birdhouses that reflect the character of old N.C.
After taking this frame from the second story, I went downstairs to look for more trouble.
I could hear a lot of chirping on the first floor. It seemed that multiple birds were inside. A mother wren was making quite a racket, frenetically flying back and forth among the rafters of the schoolhouse. Following the source of all the chirping, I found a dilapidated nest on the floor near a pile of lumber, and two very young baby birds nearby... the source of the commotion.
Jeff knew what to do, so I called him in for a look. He put the nest back where it belonged, tucked it into the rafters, and then picked up the kids and carefully placed them back in the nest. "Mom" was pleased, although she still put up a fuss as we backed out of the room.
(Please don't worry about handling baby birds in a situation like this. The parents will NOT abandon them. Birds have a limited sense of smell and cannot detect human scent. That old advice we learned as kids turns out to be a myth.)
