Communication is a part of our everyday life. We greet one another, smile or frown, depending on our moods. Animals, too, communicate, much to our surprise. Just like us, interaction among animals can be both verbal or non verbal. Singing is one way in which animals can interact with one another. Male blackbirds often use their melodious songs to catch the attention of the females. These songs are usually rich in notes variation, encoding various kinds of messages. Songs are also used to warn and keep off other blackbirds from their territory, usually a place where they dwell and reproduce.
Large mammals in the oceans sing too, according to adventurous sailors.
Enormous whales groan and grunt while smaller dolphins and porpoises
produce pings, whistles and clicks. These sounds are surprisingly received by
other mates as far as several hundred kilometres away.
