Wren's Return

I was out in the very back garden when I heard the familiar wren shouting. And then there he was going in and out of his summer wren house on the tree near my head. 
You will have to take my word for it because I do not want to disturb him by taking photos.
Last year he stuffed this nest box with sticks to keep other birds from using it. Then he went off to start his couple of nests in the pines. Apparently he has a few mates just to keep the population growing
