Many animal languages are relatively simple. They consist of simple declarations of the animal’s immediate intentions, or straightforward statements of how it is feeling at that very moment.
Usually the language can only convey a limited number of messages. Yet in some cases, the information sent in the message is really quite complicated. For example, some animals can pass on to another, detailed instructions concerning the exact position of food. Some animals have developed means by which to increase the amount of information they can pass through their language, either by using a larger repitoire of messages or by conveying more detail in their existing messages.
