Yesterday there was much fluttering and chirping in the garage as a bevy of Carolina wrens flew in and out the window. For the second or third year in a row Mama Wren had nested on an upper shelf full of old vases, tucking her abode in between a green vase and a clear one, using the shelf in between as a patio of sorts.

The fledglings must have been practicing their first moves over the last few days, when there seemed a confusing preponderance of bird life in and around the garage. There were suddenly wrens everywhere: in the holly trees, at the bird bath, at the feeder and the suet block.

Now that the nest is empty, I climbed up to take a look. How still and silent and abandoned it looked. One fact struck me: Unlike human nests, which empty and refill many times over a lifetime, when bird’s nests empty … they stay that way — at least for the season.
