Modes of Communication

Different modes of communication have different characteristics that make them more or less effective for certain types of signal.  One of the main modes of communication, and the most common is visual communication.  It is common but diverse and includes permanent signals and temporary signals.  Permanent signals include coloration, while temporary signals include things like smell and sound.  Visual signals have three things in common; they are fast at conveying information, can work over long distances, and are restricted to line-of-sight.  Meaning, they are dependent on environment.  Both types of visual signals can be tasking or easy. Permanent signals are usually easy to maintain but costly to produce, like feathers.
Auditory signals are fast and can travel long distances. But, they are always temporary, and they require constant energy, like a frog croaking. Auditory signals are also easier to eavesdrop, which can be harmful to prey animals trying to signal predators.  A positive is that locating the source of the signal becomes more difficult.
Olfactory signals are smells and are a very slow signal.  The signal is restricted by air movements, and are useless for signals needing quick speed, like marking territory before rivals can. Although, they are good for persistence, as they can last a while.
Tactile communication is gestures between two individuals, usually during mating, or most commonly, during grooming.

Humans use signals for communication literally every single day. Our main ways of communication are auditory as well as visual; talking and facial expressions.
