The Common Crane is an omnivore: - Plant matter: roots, buds, grass, grain (oats, barley, wheat) — important in spring and autumn. - Insects: beetles, grasshoppers. - Small animals: worms, snails, frogs, lizards, small rodents. - At feeding sites: barley (Lake Hornborga has provided food since the 1990s to keep the cranes away from young crops).
