communication signals
Ways of conveying meaning
Communication signals are behaviors, sounds, or displays that convey information between organisms.
Animals use communication signals to attract mates, warn of predators, establish territory, or coordinate group behavior: The firefly's flash is a communication signal to potential mates.
The term appears in biology, linguistics, and telecommunications, covering everything from birdsong to radio transmissions.
