Decorah North, Mississippi River Flyway

Diet
The omnivorous Sandhill Crane feeds on land or in shallow marshes where plants grow out of the water. Their diet varies widely with location, season, and food availability, but may include the roots of aquatic plants, seeds, grain, berries, tubers, rodents, snails, frogs, lizards, snakes, and nestling birds.

Nesting
Sandhill Cranes use cattails, sedges, burr reeds, bulrushes, and grasses to build their nests, using dried plant materials early in the season and adding green materials later on. After building a foundation or mound of larger materials, one crane (usually the female) forms a cup-shaped hollow lined with smaller stems or twigs. Nests may be 30-40 inches across and 4-6 inches high. In non-migratory populations, egg-laying can happen any time between December and August. In migratory populations, Sandhill Cranes usually lay their eggs in April and May. Their eggs are a pale brownish-yellow to olive, with irregular brown or grey markings. They lay one to three eggs per clutch and produce one brood per year. Both parents incubate eggs for 29-32 days, and young leave the nest shortly after hatching.
