Ostriches eat all kinds of food. During their growth, they mainly feed on stems, leaves and fruits, among which flowering shrubs, creeping plants and cucurbitaceae plants are the most popular. Moreover, ostriches are big, with flat and sharp mouths, and can peck at the fruits on the trunk.

Distribution range of ostriches
According to the characteristics of birds in different places, ornithologists found that the world can be divided into six geographical regions, each region has unique birds, and the birds in the same region are generally very similar, which is the result of evolution and adaptation to the environment, among which ostriches are distributed in Isoptera and Africa.
Ostriches are widely distributed in arid areas of Africa with little rainfall. In Cenozoic and Tertiary, ostriches were widely distributed in Eurasia. Not only ostrich eggs but also leg bones were found in Zhoukoudian, the famous birthplace of Beijingers in China.
It was distributed in Africa, Syria and Arabia in modern times, but now the ostriches in Syria and Arabia have disappeared. Their distribution is from the Sahara desert to the whole Africa, and Australia introduced them in 1862 ~ 1869, forming a new habitat in the southeast.
