Besides living on grasslands, ostriches also live in the semi-deserts of Africa. Being the world's largest bird, they are 2.5m tall and weigh 115kg. Ostriches are so heavy their wings cannot lift them up, and they run on the ground instead. Ostriches are fast runners, reaching 64km/h at most. They have excellent eyesight and can see predators from far away. Ostriches can go without water for a few days. They eat plants, seeds and berries. They are very suited for life in the desert. An ostrich nest can have 15-50 eggs. The gigantic eggs are 15cm long. Chicks can run soon after hatching. Several nests of chicks group together and travel with 1 or 2 adults in search of food and water. The whole group may have 100 chicks in it! The chicks can grow as tall as an adult ostrich after a year.
