My backyard is very bird-friendly. I have feeders, birdbaths, bushes, trees and Audubon-approved bird houses. We don’t use chemicals on the yard. A haven for birds, right? Wrong. They come to my yard for food and water and cover, but have rarely nested here.
My next-door neighbors know little about birds and can only name the most common. They put chemicals on the lawn, have dogs* and an indoor/outdoor cat. Years ago they put up some ridiculous looking bird houses (shaped like birds) and guess what. Birds nest in them every year and build nests in their trees.
