Birds communicate with each other in a variety of different ways and make some of nature’s most musical sounds. What we generally call bird songs are often associated with courtship and mating rituals and tend to be long and complex and sound tuneful to the human ear.
Bird calls are generally shorter sounds that serve a more functional purpose such as alerts and alarms or for keeping in contact.
Birds also use make non-vocal sounds produced with their wings, feet, tails, and bills such as drumming, beats, clapping, and snaps. These sounds can be used during courtship displays or for other communication.
