Reproduction: Ostrich matures at 3-4 years of age. The breeding season ranges
from August to March, though it varies according to the region where they live.
She lays about 10 to 20 fertile eggs shortly after mating. Eggs are laid in a scrape
made by the female. A single nest may be used by many females for laying purpose.
Each female lays egg usually every alternate day. The white to yellowish egg
may be 6-8 inches long and weighs up to 2.3 kg. In the wild state, eggs are often
partially covered with sand in day time. The incubation is carried out by both
sexes and the sturdy and dappled chicks are hatched after 5-6 weeks of incubation
Behaviour: Ostriches are diurnal birds and forage during day light hours. They usually travel in bands comprising five to fifty birds. The male fights for a harem of three to five hens. The male sounds a hollow booming call to attract the female. Another interesting behaviour of ostriches is that they congregate with zebras, antelopes and other large grazing mammals for mutual benefits.
Life span: They are said to live 50 years.
