Grassland crane species primarily eat insects and seeds and have relatively short bills. Cranes with medium length bills eat insects and seeds from grain fields, in addition to a wide variety of plant and animal matter from wetland areas. Cranes with long bills use one of two feeding strategies. "Diggers" dig holes in wet mud to look for tubers, root vegetables like potatoes. The holes are sometimes 1.6 feet (0.5 meters) deep. "Catchers" look for live animals on the ground.
