Feeding

As a woodpecker, its diet is composed greatly of insects, which it gains from drilling into bark. Gila woodpeckers are omnivorous, and do take fruits, nectar, seeds, as well as lizards, eggs, worms, and even young chicks of small birds. They are even known to hang on human placed hummingbird feeders and sip up the nectar.
