What kind of sounds does a 300 pound bird make?

A 300-pound bird, such as an ostrich, typically produces deep, resonant sounds that can include booming calls, hissing, and low-frequency grunts. These vocalizations are often used for communication within their flock or to establish territory. Their sounds can vary in intensity and duration, reflecting their emotional state or social interactions. Overall, the sounds are quite different from smaller birds, often being more powerful and less melodic.
