Well, we've noticed a pair of them building a nest in the bird house we put up a couple of years ago. However, the wrens will often build nests that they never use - decoy nests if you will. Since the building of the nest in our birdhouse, we haven't really seen either of the wrens. That doesn't mean they aren't using the nest though. Last year we thought they'd nested somewhere else and it wasn't until the pair started to feed the babies that we realized that they had actually occupied the nest. Like I said, this was less than 2 feet from our kitchen door which has an all glass storm door and which we keep open to allow light into the kitchen most of the time.
I'm giddy with excitement and will keep you posted on whether we have babies this year or not! In the mean time, here's a painting I did of one of our fledglings last year.
