Egg of Ostrich
Ostrich eggs are the largest of any living bird, which doesn’t come as a surprise, considering ostrich itself is the largest living species of bird in the world. A female ostrich can lay 40-100 eggs per year, which roughly amounts to one egg every second day from the mid March till the mid August. An ostrich egg measures approximately 6 inches in length and 15-18 inches in circumference. On an average, its weight is close to 3.1 lbs (1.4 kilograms). The color ranges from pearl white to cream. With a thickness of 0.06 inches, the ostrich egg is quite strong as well. Though it is the smallest when we go by the ratio of the weight of egg to the weight of the bird. In terms of nutrition content, an ostrich egg can provide a whopping 2,000 calories. Other than 47% of proteins and 44.3% of fats, these eggs also contain calcium, phosphorus and vitamins like vitamin A, vitamin E, riboflavin and thiamine. Eggs are laid in a communal nest called a dump nest, which can hold about 60 eggs at one time the female ostriches incubate the eggs during the daytime, while the male ostriches do the same at night. The practice comes handy for this species when defending themselves and their nests from predators. While the greyish-brown females blend with the sand during the day, males with their black feathers become virtually invisible in the darkness of the night.
a chick is almost at its full-grown height; at 3 or 4 years, it will reach maturity. An ostrich can live 50 to 75 years.
The ostrich is the largest and heaviest living bird. As its species name, camelus, suggests, the ostrich was once known as the “camel bird” because of its long neck, prominent eyes, and sweeping eyelashes, as well as its jolting walk. Also, like camels, the ostrich can tolerate high temperatures and go without water for long periods of time. As it is so heavy, this flightless bird that can never take to the skies; instead, it’s built to run. Its long, thick, and powerful legs can cover great distances without much effort, and its feet have only two toes for greater speed.
