A flowerpot fitted with a 1-1/4-inch entry hole offers housing for small birds, such as the chickadee, nuthatch, tufted titmouse, and wren. Site the house away from high-traffic areas of the yard and where nearby trees and shrubs offer shelter, giving birds the privacy they need to nest, hatch, and raise broods. Locate the birdhouse where it is protected from late-day sun in summer and wind in winter. Remove old nesting material from the birdhouse annually in autumn, when you are certain the breeding season is done.
Gather the materials. Drill a hole in a fence, wall, or other surface to mount the birdhouse.
Slide a washer over the bolt, then push the bolt through the pot's drainage hole and into the fence or other surface. Slide a washer over the exposed end of the bolt; twist the nut onto the bolt and tighten it to secure the pot.
Drill the 1-1/4-inch-diameter entry hole in the wooden plaque, about 1-1/2 inches from the bottom edge. Sand smooth the edges of the entry. Paint only the outside of the wooden plaque to make it more weather-resistant. Let dry. Press the plaque into the pot until it is firmly wedged in place. A perch is not necessary and might provide a foothold for predators.
