How cool, its fun when you discover a new bird in the area.
While wrens are a fairly common bird I didn't realize I had some near me until last year when one surprised me by taking up residence in an 'ornamental' bird house I had. It was in an area I frequented in my yard and it would chatter to me whenever I came too close her babies. :)
I put it up a couple of weeks ago and within a day or two my little friend has started visiting several times a day. I'd love for Jewel to pop in and give us some updates on her Igor as she was the one who inspired me to get my first hummingbird feeder. :)
