Cover crops provide bed and breakfast layover for migrating birds

After harvesting a corn or soybean crop, farmers may plant a cover crop for a variety of reasons—to reduce soil erosion and nutrient runoff, increase organic matter in the soil, and improve water quality. Now there’s another reason. University of Illinois research shows that migratory birds prefer to rest and refuel in fields with cover crops. “Here in the Midwest, we’re in one of the major flyway zones for migratory birds, where there once was plenty of habitat for grassland birds to safely forage and rest during their migration. Now that agriculture is the dominant landscape, they’re finding it harder to get the resources they need on the way to their breeding grounds,”  “We think cover crops, such as cereal rye, likely provide migrating birds with more vegetation and a safe area to escape from the elements and from predators,” Wilcoxen says. “Cover crops also increase insect abundance, another food source for birds. The increased number of insects allows migrants to fuel up faster and move on to their breeding grounds.
