No, ostriches are not faster than cheetahs. While ostriches are the fastest birds on land and can run at speeds of up to 45 miles per hour (72 kilometers per hour), cheetahs are the fastest land animals and can reach speeds of up to 60 to 70 miles per hour (97 to 113 kilometers per hour) in short bursts covering distances up to 500 meters.
Ostriches use their speed primarily for escaping predators, and they can maintain their high speed for longer distances compared to cheetahs. Cheetahs, on the other hand, rely on their incredible speed for hunting, but they can only maintain their top speed for a few seconds before they need to rest.
In summary, while ostriches are impressively fast, cheetahs are faster and hold the title of the fastest land animal.
