We can all sense whether an animal is hostile or friendly by its sound … but did you know birds growl too? Find out more on today’s Creation Moments Minute.
Researchers say that almost all animals make high-pitched sounds or low-pitched sounds. Even the higher-pitched voice of birds has a barking mode that can be seen on a graph and heard when a slowed-down recording is played. Animals make lower, harsher sounds when they’re being aggressive. This is the growl. When friendly, an animal makes higher-pitched sounds. The bark seems to mean that an animal is neither hostile nor friendly, simply curious. Human speech follows the same general pattern.
These universal features of communication reflect the work of our Creator who intended for many different kinds of creatures to coexist. He gave us all a universal method for understanding important basic messages like fear, aggression and joy.
