What are the reasons animals use sounds?
Animals use sound to warn others to stay out of its territory and also to attract a mate. Crows are highly intelligent birds that have a complex language system. They make at least twenty five different sounds which include growling, squawking, squealing, cooing, and rattling. They use these different calls to identify themselves and communicate with other birds. They also have an emergency call to have other crows come quickly to help. A group of crows is called a murder.
