I received these instructions from a cavity nesting songbird, one that serenades me while I’m working in the garden: the common House Wren.
Step 1.In the absence of a hollow tree, find a small box with a hole in it. Stuff the box with tiny twigs (about 600, give or take a hundred). Leave some room at the top for bedding and the kids. Oh, and in your spare time, stuff every other nest box in sight with twigs to discourage the competition.
Step 2. Scavenge some soft material for bedding (you don’t want the kids flying around with a stick up their butt). Fragments of insulation from a nearby dog kennel work well.
Step 3. Sing loud and often to let the world know what you’ve done. And that you own it.
