I wondered why the previous owners of our house did not take this nice birdhouse with them to Sante Fe, New Mexico. During the day of the inspection, I realized why. We have a very happy couple of house wrens tending to their young. It is quite fascinating to watch the pair forage throughout the yard for insects and other invertebrates. Each bird lands about twenty feet from the box and gives out a low-pitched rattle, to which the nestlings respond with a chatter of squeaking. The parent then flies to the box, typically alighting on top of it, and when the moment is right, quickly ducks down and into the cavity. Having nesting birds in the backyard was certainly something I was not expecting when we moved here. I wonder when they'll fledge? I'll be keeping an eye out.
Tomorrow I'll crop some of the photos to show just exactly what types of insects that these tiny parents are feeding to their babies.
