Midterm Prep Flashcards
Causes of neurotic behavior in captive primates
boredom
chronic stress
age
changes in diet/medication
sickness/disease
public presence
construction
hand-reared
TRUE or FALSE: A primate doing abnormal behaviors is a coping mechanism and has NOTHING to do with intelligence
TRUE
Define total social isolation
hand-reared by a person. No other species with them, no access to conspecifics AT ALL
Define partial social isolation
pulling infant from mom but housed near other conspecifics
What are some abnormal primate behaviors
self-biting- they don’t necessarily associate that that is their body
slooting
grasping, rocking
floating limb, jumping up and down
mouthing, appetite disorder
running, bouncing in place
head banging, repeated somersaults
pacing, hair pulling
head tossing and weaving
Things that help decrease abnormal behavior
more personal time spent
more enrichment
medication
visual boundaries
training
stress reliever methods
Types of primate communication
vocalizations (New World have more)
facial expressions (Old World have more)
body language
olfactory (urine washing)
tactile (grooming)
Examples of primate body language
Head bob (starting threat. Bubba)
Forebob (head and shoulder bob)
Crouch (threat)
Stiff legs
Bounce
Flip and Hairup (baboons and other Old World Primates. Precursor to aggression)
Tail up (submissive if between legs, up high if threatening)
Head shake- dependent on species for meaning
Olfactory- push out chest for other to smell
What two things does tactile behavior involve
- Grooming
- Foraging- lowers stress level
What are four facial expressions expressed by primates
- Lip smacking- Old World more. Usually goes with grooming as a social glue
- Presenting- grooming
- Lie down- can be another way of presenting
- fear grin- baboon
When will a primate challenge a dominant
When they see weakness
What could it mean if a primate is refusing or being slow to do a behavior
A challenge
What are some primate vocalizations
screeching
yakking (geic)
chirp-like clicking
dog-like bark (seems to occur when animal is separated temporarily from the rest and is about to rejoin them. Let’s everyone know there is a dominant in the area.
What are the differences between Old World and New World primates
Old World: less vocal, more confident, relationship-based, bite from challenge (bond with human can be stronger), keeps track of wins/losses
New World: more vocal, less confident (afraid), less relationship-based, more likely to bite from fear (human bond not as strong), don’t care as much about keeping score
When do primates begin to think about their place in the heirarchy, and why is this especially common with singly housed primates.
When an animal is satiated with enough food, they start thinking about their place in the heirarchy, and food isn’t their first priority anymore. Small and male monkeys get to this point faster.
Singly housed primates need to look to the trainer to fulfill and help them with heirarchy because they don’t have a real troop.
