Question 8 of 10
How many vertebrae are there in a giraffe's neck?
Why, in question 7: What is the largest bird in the world?
The answer is the ostrich. An adult male can stand over 2.5 meters tall and weigh more than 100 kilograms. The rhea, its South American relative, is much smaller, and the eagle and the albatross, though large in the air, weigh much less.
Too big to fly
The ostrich cannot fly: its wings are small for the size of its body and serve for balance while running and for display. In compensation, its legs are long and strong, and each foot has only two toes, which helps it run.
In Brazil, the bird that most resembles the ostrich is the rhea, the largest bird in the country. It lives in grasslands and savannas, also cannot fly, and it is the male who incubates the eggs and cares for the chicks, often those of several females at the same time.
The ostrich's eye is larger than its brain, about 5 centimeters in diameter, one of the largest of any land animal. Its sharp vision helps it spot predators from afar in the open savannas.
Ostriches live in the savannas and dry regions of Africa, and they are also raised on farms in many countries, including Brazil, for their meat, leather, and feathers.
