"An ethogram is a catalog of an animal’s behavioral repertoire, detailing the different forms of behavior that are displayed by an animal. In most cases, it is desirable to create an ethogram in which the categories of behavior are objective, discrete, and do not overlap with each other. Definitions should be clear, detailed and distinguishable from each other.
Ethograms can be as specific or general as the study warrants. A research project dealing strictly with aggressive behavior in chimpanzees can be composed simply of the various forms of aggression displayed by that species. Alternatively, some studies seek to describe all facets of a particular animal's behavior, and the appropriate ethogram will comprehensively categorize any and all behaviors that may occur." from the AZAA, Behavioral Advisory Group
