Ready for bluebirds

As March melts toward what we hope is the spring of April, anticipation must be building for gardeners. Though my parents had big and bountiful gardens on the farm, for some reason I don’t have the itch or niche for raising vegetables. I will let others enjoy the garden and will barter for their produce when it comes of age.

My March days are full of anticipation of what’s coming to the fields, not the gardens, and I’m not talking about alfalfa, clover and corn. I’m dreaming of bluebirds on sunny, warm spring days. I’m working on their lodging so it’s ready when their flight arrives.

A few weeks ago, as March dawned like a house cat rather than a lion, I got at the task immediately, while the field was still covered with several inches of crusted snow. But considering the speed with which that snow was leaving, and the promising longe-range forecast, I knew bluebirds could arrive early. I usually note their return the first week in April. But March has been noted in my journal before, and could be again this spring.

I keep adding nesting boxes—there are now five—but the one the bluebirds prefer was the first I ever built. It was rather crude, made of weathered shed boards from an uncle’s farm. One spring I replaced it with something bigger and better (I thought) and moved the original a couple of hundred yards farther north on the edge of the field, where it meets the town road ditch.

When the bluebirds returned, they promptly found and claimed the box that I moved—their old home—proving new and improved isn’t always better. The tree swallows took over my new project, as they have at other boxes intended for bluebirds. So be it; the two species get along fine in the same neighborhood, which also has bobolinks nesting near the ground in the hayfield.

Several years ago I improved ventilation in all boxes in hopes of helping the birds and their chicks survive prolonged days of hot sun; one July I found dead bluebird chicks in the nest after a brutal stretch of heat. Last year, I repaired a rotted corner of the tree swallows’ box with a piece of aluminum cut from a Leinenkugel’s beer can. The swallows didn’t mind the advertising. This spring, the boxes pretty much needed only cleaning, though one roof required refastening.

During the inspection, I was pulling old grass and cottony seed balls of goldenrod from one box when something jumped from the nest mess. A short-tailed shrew hit the snow and scampered for long grass. A shrew shack! I was wearing gloves, but nevertheless found a stick to finish the clean-out.

After a walk through the woods, sinking several inches into the granulated, melting snow, I started back through the field toward the road. I passed the readied bird boxes, wondering when bluebirds and swallows will return to this field, along with bobolinks and meadowlarks. The day was warm enough, with a blue sky, that it felt it could be any hour. But I knew it was several weeks away. Spring will come; it always does. The bluebirds will tell me when.
