We know that animals communicate. But why do they communicate? The first reason is to warn off other animals from their territory. Through 
their communication, they challenge rivals and establish their superiority. The courting ritual of animals is carried out through their communication. Some animals display body parts to show they are ready to mate or to attract the opposite sex. Others stand or walk in a particular way, while still others release particular scents. Many animals have characteristic mating calls that are unique to the species, thus allowing them to mate only with members of their own species.Animals also make “food calls” that attract a mate, their babies or their friends to a food source. Some signals are made to warn other members of their group of a threat. There are also some signals that are used to modify the meaning of signals that follow, or came earlier. In short, communication helps animals to co-ordinate the vital functions of their lives …mating, gathering food, hunting, caring for their young, marking their territory, and defending themselves
