An ostrich's flat mouth has two nostrils and breathes through a visible membrane. Ostriches use evaporation from their lungs to spread their wings to regulate their body temperature. In case of high temperature, they open their mouths to breathe and spread their wings to increase evaporation and water consumption.

Ostrich information:

Ostrich is a two-toed bird, which runs very fast, with a speed of 60km/h for 10 ~ 20min.

Ostrich's vision is very good, with two eyes accounting for 1/3 of the head, and a "third eyelid", which can block the wind and sand and protect the eyes. The field of vision is 300m m ... The ears are behind the head and can be opened and closed. They are covered with fine feathers, just making up for the distance of 60 meters out of sight. In addition, the flexible neck enables it to observe the surrounding environment and distinguish companions from enemies at a distance.

An ostrich has wings, but it cannot fly. Its main function is to balance the body, cover the hairless thighs, keep out the cold and resist foreign provocations. It can also be used for courtship during mating. Male ostriches often use their wings to clean the nests of female ostriches, while female ostriches often peck chickens and young birds with their wings.

The ostrich has well-developed legs and no feathers. An ostrich's foot has only two toes, and there are claws in front of them. The claws of its big toe are very sharp. When it is threatened and has no way to go, it will use its feet to protect itself. Strong legs enable it to run well, turn flexibly and resist natural enemies.
