Don’t let their sweet song fool you. Chickadees and their cousins, titmice, are pest-control champions throughout the United States and Canada. As much as 90 percent of their diet consists of insects—moths, caterpillars, flies, beetles, bugs, plant lice, scale, leafhoppers, and tree hoppers.
In winter, chickadees stay on patrol, searching bark crevices for hibernating insects and the eggs of moths, plant lice, pear psylla, and katydids.
To keep chickadees and titmice on patrol in the winter, provide some suet in a mesh bag or a feeder full of sunflower seeds. In spring, provide a nest box packed with wood chips. If possible, place the nest box at the edge of a wooded area.
