We have a wren house nailed up to our fence under an apple tree in our side yard. We saw two wrens taking a look at it the other day. It was really funny actually. We saw one bird (presumably the male) the day before, looking at the establishment and we were hopeful. The next day, the bird shows up again, this time with the Missus in tow. We know this to be a fact because the second bird already had packing material in-beak, and we all know women are the more practical gender.
The male landed first as if to say, "see? It's perfect!" The female took a look and you could almost see her saying, "what? We'd be catfood in there!" and flew off. That we thought was the end of it.
A few days later, we were sitting down to breakfast and we saw a leaf or something in the opening to the house. Then a few minutes later it was gone. Then it was back... I thought it was the wind. Well, curiousity got the better of Amy and she went out to investigate yesterday. She went right up and stood on tiptoe, putting her eye practically right up to the hole. She saw nothing at first, then a beak appeared. Before my wife could do anything, a furious flap of wings and a brush past her cheek told her we most certainly had guests. (edit: I wasn't going to throw her under the bus and mention the screaming like a little schoolgirl part, but she goaded me, so now you know. I heard it from inside the house. One of those moments where you know exactly what happened and it's as funny in your head as in real life.)
She was worried she scared the birds off for good, but we saw one of them this morning on the roof of the house, so they must be still around. But they are excellent at eluding the camera, so no visual today :(
