Up until 1941 ostriches lived in Syria, Arabia, and Africa. 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. Reproduction Exact pattern varies geographically.
Ostriches form bisexual groups with a complex structure.
Territorial males compete for flocks of 3 to 5 hens. Elaborate displays, including hisses and other noises, are often used by males to intimidate each other. Once divided into mating groups, ostriches in some areas use communal nests to hold anywhere from 15 to 60 eggs. The nest is a hole scraped in bare ground. Eggs take approximately 40 days to hatch.
