the ostrich

male ostriches have been recorded with weights of up to 155 kg (340 pounds). The feathers of adult males are mostly black, with some white on the wings and tail. It is often said that their eyes are larger than their brains.The strong legs of the Ostrich lack feathers. The bird stands on two toes, with the bigger one resembling a hoof. This is an adaptation unique to Ostriches that appears to aid in running. At sexual maturity (two to four years old), male Ostriches can be between 1.8 m and 2.7 m (6 feet and 9 feet) in height, while female Ostriches range from 1.7 m to 2 m (5.5 ft to 6.5 ft). During the first year of life, chicks grow about 25 cm (10 inches) per month. At one year, ostriches weigh around 45 kg (100 pounds). An Ostrich can live up to 75 years.
