Nature is filled with a diversity of sounds made by various life forms both day and night. Birds sing, eagles screech, snakes hiss, animals like cats, chickens, cattle, and lions make distinctive noises, while frogs croak, hyenas laugh, and monkeys chatter. Humans also make sounds like screaming, crying, talking, singing, and laughing. All of these natural sounds serve purposes like communication, having fun, attracting mates, defense, or pursuing prey.
