  1. Ethogram Notes Charting Animal Behavior

  2. Ethogram = • behavior inventory • used for quick recording of behaviors • takes 1000’s of hours for a complete catalog of behaviors • helps decrease subjectivity

  3. Ethogram Procedure • Identify behaviors • What is the animal doing? 2. Categorize behaviors • Create categories • Create sub-categories

  4. Ethogram Procedure 3. How to record behaviors? Options: A. make list of behaviors, check mark if occurs ( no matter how long it happens) B. create time budget- mark amount of time during which behavior occurred

  5. Ethogram Procedure 4. Decide who to observe - Options : A. watch one individual = “case study” • gives in depth information about one animal • ¿ what to do if individual hides, or can no longer be seen?

  6. Ethogram Procedure B. Watch several animals in a group • “Scanning the group” • Decide on time interval, scan entire group at interval, record presence of given behavior • OR randomly pick individuals, observe for set amount of time, then move to next random animal & do same

  7. Concerns • How observant / trained to recognize behaviors is the observer? ★Do you know what to look for? ★Experience really helps- (I know when the horse is going to try to buck me off…)

  8. Concerns 2. Effect of the observer • Wild animals do not behave “normally” in presence of humans • Habituation? • Hide observer?… (behind a blind?)

  9. Concerns 3. Inter-observer reliability • Do I see / interpret same behaviors as you? • Are two observers seeing / recording same behaviors? • Are they recording the same behaviors, but naming them differently?

  10. Concerns Other Concerns? • What if you can’t see your animal? • What if your animal sleeps the whole time? • What if the animal doesn’t seem to be doing anything? (Become a closer observer!) • Others?
