Question

what is used by birds to communicate?

Answer 1

The song of birds can be soothing and inspiring, but birds sing for more than just the beauty of it. Birds use song, call notes and behavior to communicate with each other. Birds use sound and action to scare off predators or warn other birds about danger, to attract a mate or to defend one's territory.
