Why giraffe is a silent animal?

Giraffes are not silent animals. They make a variety of sounds, including moos, whistles, and grunts. However, they are generally quieter than other animals of their size. This is because they have a long neck and a small trachea, which makes it difficult for them to make loud sounds. Additionally, giraffes are often found in open areas where there is a lot of noise, so they may have evolved to be quiet in order to avoid attracting predators.
