Frank was in and out of the Society's nest box at least three times last night! And when I popped by this morning, he was inside, staring out at me. He's a little like Sally when
she discovered the white concrete perch: she completely ignored it for over a year, and suddenly it was her favorite place to be.
Apparently, all of Frank's activity got the other Finsters interested in that nest box, since this morning Ginger and Cinnamon both popped inside. They didn't stay very long, though.
I'm not sure if Frank slept inside the box with Earl Grey (and probably some Finster friends) last night, but chances are good that he did, since he didn't sleep on top of the box, as he usually does. He spent a few minutes on the box's porch when the lights went out, peeping loudly, which is another good sign. But I didn't want to watch the birds too closely, for fear of disturbing everybody too much. I also missed the birds leaving the box this morning, so there's no proof. But I'll keep watching.
