We all know that animals do not have the ability to use language as the medium of their communication. But, they do have other abilities of conveying messages to other animals amongst which use of body language is the most important factor. The messages can be of many types like conveying food location, calling for mating rituals, danger alarms, appreciation of good deeds like helping other animals in dangerous situations, etc. There are different types of animal communication, which will be looked at in this segment. Different species use different types of communication. There are two main types of communication in animals and consists of a few subtypes under them.

Verbal Communication

Sounds are one of the most common types of verbal communication in animals and the majority of the species use them as the medium to convey messages. Bats usually follow sound waves to communicate. They mostly rest in the morning and become active at night to search for food and do other tasks. All the birds communicate through their chirping and it is ultrasound waves that they use. Mammals, generally, make use of sounds to give calls to other members of their community. The smaller animals squeak and larger ones rumble. It is found out through studies that, an animal with the smaller head can produce really large sounds and also receive a greater frequency of sound! Whales are the perfect users of sound waves. They have a whale song, which they repeat after regular intervals.

Non-Verbal Communication

Facial Expressions
This kind of communication is mostly found in dogs. When they are angry, they show their teeth snarling and raise their ears. On the other hand, when they are frightened, they pull their ears behind with the mouth open. In birds also, when the parent bird brings food for the offspring, the ‘begging expression’ can be observed on its face.
