Ostriches are herbivorous living mostly on plant matter, but they occasionally eat animal remains left by carnivorous predators. They are very selective feeders, taking the seed heads of grasses and certain flowers and seeds. They sometimes eat locusts. An ostrich in captivity requires 3.5 kg of food per day. They can survive without water for long periods of time.
