Growers are beginning to understand that common birds can be of uncommon value to fields, lawns and gardens.

Many avian species earn their keep by eating insects and small mammals, and destroying weed seeds.

“Commercial growers are turning to birds as an alternative or supplement to pesticides,” said Marion Murray, an Integrated Pest Management project leader with Utah State University Cooperative Extension. “But you have to have the environment or habitat before inviting them in.”

That means mimicking nature by providing plenty of food, water and cover. Put up some bluebird boxes or nest boxes for raptors, said Marne Titchenell, a wildlife specialist with Ohio State University Extension.

“Monitor the bluebird boxes so sparrows don’t take over,” she said. “Brushier habitat provides protection for insect-eating songbirds. Allow the edges of your woodlot to grow up a bit. Berry-producing shrubs are excellent things to have around for all kinds of wildlife.”

While it’s great to have specialized bug hunters around, recruiting should be directed toward a variety of species, said Margaret Brittingham, a professor of wildlife resources at Penn State University.

“What we don’t want to wind up with is having a monoculture with birds as we frequently do with plants, inviting problems,” she said.
