Since Japanese Beetles spend much of their adult life in plants off the ground and subsequently flying from plant to ground and back again, birds such as Purple Martins and other swallows are a perfect fit for eating them. Starlings and Grackles are significant predators of both the adults and the larvae. Meadowlarks, Cardinals and Catbirds are known for targeting the adult beetles as a food source. Other Japanese beetle grub consuming birds include Crows and gulls. In addition to the wild bird populations, chickens are also eager to volunteer for snacking on Japanese Beetles.
