Auditory communication is the sound an animal makes. The sound may be one that comes from the animal, or it may be a sound the animal makes when it interacts with an object.
Pump Up the Volume
 Male American alligators use a combination of sounds and displays to get the attention of females when they want to mate. An alligator roars, slaps his head against the water, taps the nose of the female, nudges her, and shoves up against her to get her attention.
Sound Reasons
 ome animals have different vocalizations for different occasions. Coyotes are one of the noisiest animals in North America. They use a series of barks, yips, and howls to mark territory and to let other coyotes know where they are. |

Were You Invited?
 Lots of animals vocalize when an intruder comes too close to or invades their territory. You have probably heard a dog start barking when someone comes close to its house. Red squirrels make a series of loud rattles, screeches, and yips to warn off intruders.
Talk to the Animals
 The dolphin has a wide range of vocalizations. Some scientists think they have a language. Scientists are working to see if humans can communicate with dolphins. Each dolphin also has its own unique whistling sound that it uses to identify itself. Dolphins use sound or echolocation to locate food. They have sacs in their foreheads that they use to make clicking sounds. The sounds travel through the water and when they hit something, bounce back to the dolphin.
