Yes a little wren is building a nest in the box on the back garage. I had forgotten all about this nest box until Steve trimmed the wisteria that was growing rather wild over the garage. Hopefully, they wrens will bring up their little ones here but having read on RSPB website about their nesting habits, I am not so sure. Apparently the male builds a number of nests and then lets one of his wives choose which one to lay her eggs. Yes they have more than one wife sometimes too!
