The sound that a horse makes is called a neigh, also known as a whinny or a bray. According to, horses make different sounds to communicate with other horses or humans. For example, horses usually whinny softly and gently when they hear a friend coming and the friend is not far away. This soft and somewhat guttural sound, which is similar to a grumble, is called "bubbling" and can often be understood as an invitation to come closer. Stallions often use a very deep and long blubbering sound to arouse the interest of mares, as if to say "Look, Im a great one!". Very confident horses can sometimes also be recognized by a short and piercing neighing cry. If there is food, it is not uncommon for it to sound very energetic and expressive. A high-pitched, piercing squeal is also heard from horses in some situations. It can be a sign of anger and exuberance, but it can also be a warning.
