Simply put, the numbers reveal the distance at which trust breaks down between your own human self and your wild neighbors. Webster defines protocol as the ceremonial forms and courtesies that are established as proper and correct in official relations between parties. Such protocol might be based upon a species-specific instinctual behavior, or in certain other instances upon learned behavior agreed upon by individual animals from two or more different species. The classic symbiotic relationship between clownfish and anemone offers an instance of the former. The historical relationship between lion and Bushman is an example of the latter.
Protocol is different than symbiosis.
Symbiosis implies a physical codependency advantageous to two dissimilar species. Protocol is, instead, a social behavior established between individuals. Regard it as the etiquette of an ecosystem. Because protocol inevitably implies varying degrees of conscious behavior communicated between species, it may be unfairly construed to be anthropomorphic which is the precise reason we never encounter the concept within the standard lexicon of field biology. But who can honestly say where instinct ends, and a mutual conscious regard between individuals begins.
