Make Room for Sparrows
And keep them apart from other small birds, suggests Chris Peterson in his instructional for homemade birdhouses and birdfeeders, Build-It-Yourself Birdhouses. Sparrows are an aggressive intruder after all, crowding out other small birds. His Sparrow Milk Carton design improves on the flimsy half-gallon cartons popular with recyclers. “This birdhouse is much sturdier and adapted to the needs of a songbird,” he points out. The sides are made from cut and bent sheet metal and the floor has a clean-out door for refreshing the shelter between broods. Place this bird residence close to the house and away from other songbirds.
