any vocal sound an animal may make that can provide information about its internal state, communicate with others, manage the behaviors of others, or alert others to dangers. Some mammals, not unlike humans, possess a larynx, which vibrates to produce sounds, that are then amplified using mechanisms specific to the animal. For example, whales may use blowholes and amphibians may use throat sacs in vocal production. See also vocal communication.
ANIMAL VOCALIZATION: “Animal vocalization refers to any sound an animal may make to communicate a message to others – for example, a whining dog may want food, water, or to play.”
