An ethogram is a catalogue or inventory of behaviours or actions exhibited by an animal used in ethology.
The behaviours in an ethogram are usually defined to be mutually exclusive and objective, avoiding subjectivity and functional inference as to their possible purpose.
Objectivity and clarity in the definitions of behaviours also improve inter-observer reliability.
The definition may be arguable, but if it is stated clearly, it fulfils the requirements of scientific repeatability and clarity of reporting and data recording.
[10][11] Ethograms have also been applied to research concerning the behavioural response of animals to the presence of humans.
