Vultures make a variety of sounds, including honks, grunts, and whistles. These sounds are used to communicate with each other, and to establish dominance. The sound of a vulture is often described as a "honk", but it can also be a more guttural sound, or a high-pitched whistle.
Vultures are not known for their vocal abilities, and their sounds are not considered to be particularly pleasant. However, their calls are an important part of their communication system, and they play a vital role in the survival of the species.
