Auckland Zoo - Chimpanzee History - Part 2/2 (Groupings/Breeding)
For context to the discussion below, the tea-party imports were as follows:
1956:
0.1
Janie (1952-2013)
0.1
Minnie (1953-1964)
0.1
Josie (1954-2000)
1.0
Bobby (1955-2004)
1959:
1.0
Nick (1957-1961)
1.0
Charlie (1957-1971)
0.1
Siss (1957-1971)
0.1
Little Jane (1957-1962)
The chimpanzees initially lived in these two groups, but evidence suggests Minnie moved across to the second group around 1963/1964 (to give the zoo two groups of 1.2). This is based on her miscarrying an infant in 1964, which appears to have been sired by Charlie (with the other male Bobby believed to have been a behavioural non-breeder).
Four infants were born to these imports:
0.1
Suzie (August 1964) Charlie x Siss
1.0
Unnamed (November 1965) Unknown x Unknown
0.1
Sally (October 1970) Charlie x Siss
1.0
Unnamed (July 1971) Charlie x Siss
The parents of the second infant are believed to have been Charlie and Siss.
1964 was an interesting year all round as
A Tiger by the Tail(1992) notes the orangutans moved out of the cage block that also housed chimpanzees:
Sadly, these early orangutans never really had adequate accomodation at the zoo and Topsy and Turvey lived for many years in a section of the chimpanzee cage block.
However, in 1964, the council approved the conversion of a larger cage block to accomodate the orangutans.
The day these adult orangutans were transferred across the zoo will long remain etched in the memories of many staff members…(continues).
This implies the zoo’s capacity to hold chimpanzees increased with this move. It’s reasonable to assume the cage block initially consisted of three cages (two holding chimpanzees; one holding the pair of orangutans). It likely that Suzie (born 1964) occupied the orangutan cage (or at least one of the cages) from her juvenile years onwards after they’d moved out.
Due to the challenges of accomodating the exisiting population of chimpanzees noted above, it’s reasonable to assume that initially, Auckland Zoo didn’t make a concerted effort to breed chimpanzees. In fact, there was a nearly five year gap that followed the infant born 1965 (where Charlie and Siss could have bred again, but didn’t) - suggesting some form of contraception was used.
The zoo attempted to breed its orangutans during this time - the female gave birth to a stillborn infant in 1967; and then died herself the following year.
A Tiger by the Tail (1992) made reference to the challenges in replacing these orangutans, so I’m wondering if the reduction of their orangutan population to a single male in 1968 influenced a decision to resume breeding chimpanzees, which was followed up with the births of two more infants in 1970 (Sally) and 1971 (non-surviving male).
The remaining male orangutan died in 1971 and sadly so too did the zoo’s pair of breeding chimpanzees (Charlie and Siss) and their newborn. It was a tragic turn of events given Siss had finally gotten the hang of motherhood and was rearing what was to be her final infant. Presumably housed in the adjacent cage block, it could have been an opportunity for her daughter Suzie to have observed maternal care of an infant.
As well all know, Sally was hand-reared in the house of the Head Keeper during her infancy. She was presumably introduced to her eldest sister Suzie sometime during her juvenile years.
In 1982, Auckland Zoo imported Mike (1973), who presumably occupied the third cage until he was successfully introduced to Suzie (then aged 18) and Sally (then aged 12). There’s no mention of when attempts were made to introduce the remaining trio of tea-party chimps (Bobby, Janie and Josie); but this was presumably undertaken at this time, with Mike being a nine year old adolescent newcomer (and less aggressive than you’d expect an established adult alpha male to have been).
I’d be interested to know the year the chimpanzees moved into the open air exhibit if you can recall
@ApeLadyNZ. There’s footage (and accounts on here) of the troop in this exhibit in 1989; and
A Tiger by the Tail (1992) describes it as new exhibit, suggesting it was late 1980’s. If so, this would mean Lucy (1975) and her newborn daughter Loanda (1985) were introduced to the others in the old cages, following their import in 1985. This could also explain the lengthy three year gap that followed Loanda’s death and Lucifer’s birth in 1988. Lucy (if not on contraception) could have produced another infant as early as 1986, so I’m wondering if they put Lucy on contraception until they could move them all across to the new exhibit. This also allowed her and Mike time to bond, ensuring Mike would be a protective force towards her next infant (rather than a threat), with his paternity of the next infant assured (his fatal attack on Loanda being attributed to him knowing the infant of the incoming female was sired by another male).
