Wild Chimpanzees exhibit different behaviors as dictated by a range of factors that include biology, ecology and social transmission.

While some of the behaviors exhibited by wild chimpanzees are transferred from their mothers through biology, others become integrated in the culture of a group and define the way of doing things. On the other hand, the environment/ecology dictates they type of behaviors that chimpanzees exhibit. For example, Nishida, Mitani and Watts (2004) investigated social scratching behaviors in two different game reserves (Muhale and Ngongo) he found that while chimpanzees in Ngongo used fingers to poke their counterparts, those in Muhale used Flexed fingers to stroke others.

Operational Definitions:

Sampling method: focal sampling

Data collection method: 2.5 minute intervals; 1-0 time sampling




1. Social scratching

SC [1 or 2]

One chimpanzee scratching the body of another.

1= use of fingers to poke the back of another chimpanzee

2= use of flexed fingers to stroke the bodies of other chimpanzees (Nishida, Mitani, & Watts, 2004)

2. Sounds Uttered during grooming

GC [ LS or Tc)

Sound associated with the inspection of the skin of another chimpanzee.

LS= Lip smacking sounds

TC= Teeth clacking sounds

3. Nut cracking behaviors

NC (1 or 2)

Calls made when cracking nuts that are mostly influenced by the vocal culture

1= short, high pitched pants (Vaidyanathan, 2011)

2= long hoots

4. Termite fishing behaviors

TF (1 or2)

Invasion of a termite mould with a tool made from vegetation for the purpose of extracting termites

1= repeated brush straightening to prepare the end for insertion

2= no repeated brush straightening (Sanz & Morgan, 2011)

5. Mating behavior

MB (`1 0r 2)

The use of gestures to initiate mating

1= use of auditory gestures

2= use of tactile gestures (Roberts & Roberts, 2015)

6. Feeding behavior

FB [1 or 2]

The manner in which chimpanzees prioritize feeding habitats

1= prioritize mating instead of feedinf

2= occupy high quality feeding habitats

7. Social play

SP [1 or 2]

The use of playful gestures

1= individual chimpanzee participate in playful activities such as swinging in trees

2= two or more chimpanzee engage in playful activities such as chasing one another

8. Male conflict behavior

MC [1 or 2]

During the mating activity, males are either aggressive or submissive depending on their dominance.

1; moderate aggression that includes physical contact, attacks and chasing another chimpanzee

2= no aggression where the chimpanzee is submissive (Surbeck et. Al, 2017).

9. Communication behaviors

CB [1 or 2]

Refers to the socialization behaviors

1 barking and screaming

2= pants and hoots

10. Parental care

PC [1 or 2]

Refers to the chimpanzee caring behaviors for adolescents and infants

1=Male exhibit more caring behavior

2=Females exhibit more responsible and caring behaviors
