In general psychology and anthropology a behavioral repertoire is the full range of behaviors that a person or animal is capable of: sitting, standing, eating, walking, vocalizing, etc. These are the behaviors that allow a being to function, communicate, and interact with the world. When compiling a behavioral repertoire an ethnologist or psychologist will observe and list all behaviors that are exhibited by the species.
Although behavioral repertoires are intended to be complete and exhaustive sometimes particular behaviors are hidden (deliberately or inadvertently) from the observer. Sometimes behavioral repertoires are used to reference the behaviors that an individual has exhibited in the past.
