Australasian Common Chimpanzee Population

[Zoofan15]

Huge moves upcoming for both facilities! Thought I'd offer some insight into the upcoming moves.

Going back a few years, there was recognition that Rockhampton was in need of new females following Holly's passing and Samantha being removed from the breeding program (due to her miscarriages). It was also acknowledged additional males would be required as well with Cassius ageing.

International importing was considered but not supported, so individuals within the region were the only theoretical options at the time. The initial plan was to acquire another male and three females. The male was to arrive first with two females following in year intervals. The final female would then be added (if required) a little further down the line. This was also taking into account the future transfers of both Capri and Mzuri out, and Leakey only potentially breeding once or twice more due to her age.

Jerry was the perfect candidate for Rockhampton, being a middle aged, submissive natured male who was also castrated (which wouldn't interfere with Alon's breeding). Although introductions initially progressed well, a roadblock was hit upon his introduction to Leakey who showed high levels of aggression towards him. Keepers aren't willing to risk any serious, potentially fatal injuries, as Jerry doesn't fight back. It's believed Leakey perceives Jerry as a female, due to him being castrated and his placid nature. He's also since adopted young Gandali too. She also allows him to interact with young Mzuri; so that obviously rules out any concerns of him being a physical threat. It's therefore likely she perceives him as more of a social threat.

As a result, Leakey has been separated with her youngest infant, Mzuri, for a while now. She hasn't reacted well to this change, so a move is essential as housing her in a pair with her infant isn't feasible long term for her welfare.

Over at Sydney, their troop is deemed to be the ideal destination for Leakey and Mzuri. The troop is demographically older, and the individuals themselves are some of the most relaxed chimps. Disputes and aggression are rare, so there's confidence Leakey and Mzuri will be able to integrate well. Being an entirely new troop with new individuals, Leakey shouldn't display the same aggression towards them. The males are also mostly older and gentle natured, so there's confidence in that aspect that they'll look after Leakey. Having an infant in Sydney's troop is also something that a lot of keepers are looking forward too. Being a group on the older side, it's hoped this will also benefit them socially.

With Leakey leaving, the previous plan I outlined before has had to be modified and two females will now be acquired (one from Sydney and one from Korea), as mentioned. Their arrivals will hopefully help balance out the social structure (which will otherwise be without an adult female), and this will also hopefully help them integrate seamlessly.

These two younger females will get the opportunity to breed with Alon, providing complacency for Rockhampton's troop long term. Having two babies at once will also be quite beneficial for the troop who's had some misfortunes in that aspect in the past. The two females being acquired are also unrelated to the rest of the regions breeding population, so pairing them up with Alon (another valuable male), will present more desirable genetically valuable offspring for the region in the future.

Being younger, these females will also be able to breed for a longer period (compared to Leakey). It's hoped Alon will also benefit socially, finally getting the chance to interact with chimps his age. They'll be introduced to Alon when cycling, to guarantee positive interactions from the beginning.

In regards to introductions, the female from Sydney (Sile) already knows Jerry, so it's hoped this will help with her introductions to the troop. She's a very placid female. The female from Korea is also very relaxed by nature, and her age will also hopefully prevent any negative introductions, coming in as a submissive female to a troop with a relatively youthful demographic.

On the genetics side of things, Alon and Leakey are also related so two infants are sufficient. Being the offspring of two founders, it's also essential Leakey's genetic line is diversified; she'll get this opportunity at Sydney.

In regards to the timeline, Leakey and Mzuri will be swapped with Sile hopefully before the end of this year, assuming all goes well. The female from Seoul will also hopefully arrive in the first half of 2025. She will be quarantined in Adelaide, along with a male that Sydney will be obtaining to become their new breeding male.

Thanks for sharing that information.

There’s also an article here which goes into more detail on Leakey’s aggression towards Jerry; as well as confirming the transfer of Leakey/Mzuri is scheduled for October 2024:

Aggressive female chimp Leakey, baby Mzuri to move from Rockhampton to Sydney Zoo - ABC News

Rockhampton Zoo staff said Leakey has become highly aggressive towards 28-year-old Jerry who joined the troop last year.

Staff believe Leakey sees Jerry as a social or political threat to her position in the troop.

The pair have been separated because of the risk of a potentially fatal injury.

The transfer of a castrated male between troops was a pioneering management technique within Australasia and while Jerry’s successful integration with Alon was encouraging, it’s unfortunate to get an indication of what opposition such males are up against females of the troops they immigrate into. Even the oldest, weakest males outrank the highest rankling female in chimpanzee society, so it’s clear Leakey does not regard Jerry as a male.

Leakey is a particularly dominant female, compounded by her role as alpha female of Rockhampton’s troop. Being a newcomer to Sydney’s troop may initially put her on a lower footing; but I would still expect her to have aspirations for a high ranking position within the troop.

When Fimi (1965-2012) came to Hamilton Zoo in 2008, having lived in a small troop at Adelaide, she was known as troublemaker, challenging Lucy for the alpha female role and inciting Mike to protect her in disputes. The tables turned when Mike passed in 2011 and she lost support; with Luka opposing her reluctance to submit to his authority. Her daughter Sanda (1985) has arguably thrived since her death, with the troop evolving over the last decade (especially since the birth of the infants in 2016 and 2020) to become one of the most harmonious troops in the region.

Chimpanzee Transfers and Overseas Import

Hugely exciting news that a 12 year old female chimpanzee is soon to be imported from South Korea.

In addition, transfers between Rockhampton and Sydney Zoo will provide breeding opportunities for both troops, which could see Sydney Zoo breed for the first time. It’s great to see Alon and Leakey’s valuable genetics will now be put to use with other individuals within the region given they now have two offspring together.

Rockhampton Zoo announces important changes to chimpanzee troop

As part of a carefully considered plan, Rockhampton Zoo’s chimpanzees, Leakey and her three-year-old infant, Mzuri, will be transferred to Sydney Zoo. In their place, two female chimpanzees will join the Rockhampton troop in the near future.

Rockhampton Zoo will then welcome an 18-year-old female chimpanzee from Sydney Zoo soon after, with a 12-year-old female from Seoul joining the troop in the first half of next year.

———————————————

Rockhampton to Sydney:

0.1 Leakey (30/12/1994) Chuck x Lilli; Imported 2015
0.1 Mzuri (08/12/2021) Alon x Leakey

Sydney to Rockhampton:

Monarto Safari Park - Galatea’s Infant

Some unfortunate news from Monarto Safari Park that Galatea’s infant was born last night, but did not survive. Galatea has now given birth to two infants, neither of which have survived.

While this is devastating news for the troop and all who care for them, I commend Monarto for their willingness to share Galatea’s pregnancy and the outcome with the public. They’ve historically had an open approach to discussing such matters and I have great respect for their decision to do so.

The Monarto troop have been through a lot, recovering from the early losses of Zwala, Soona and Boon; to the more recent losses of Galatea’s infants, Lani’s infant and Tsotsi. I hope should Galatea conceive again, it’ll be third time lucky; especially given what a wonderful mother she’d make.

Update from my friend’s visit (September):

Sacha has suffered a knee injury, which has limited her mobility. It’s unclear at this stage whether this has affected her status within the community, but it’s restricted her from participating in grooming sessions with the other chimpanzees. Vet staff will be investigating to ensure she receives the best treatment.

Naomi has dropped in status; as well as Shiba, whose status has yet to recover from Samaki being overthrown has alpha male. This leaves Sacha, Lisa and Kuma as contenders for the alpha female role - Sacha via status (mother of the alpha male); Lisa via social connections (she puts effort into networking); and Kuma due to her size/strength.

Furahi receives some support from the community during his displays; versus Shabani and Samaki who get no response, indicative of their low status. Liwali and Sudi will be entering the male hierarchy soon. Liwali is larger than Sudi.

Thanks for the update.

Any idea why Naomi has dropped in status? She seemed to show the most potential for being a high ranking female in the future. i imagine Shiba's drop in ranking may have also contributed as she seems to be closest with their family and Ceres's.

Sacha should be favourite for alpha position imo, but both her and Lisa's ages may prevent them from holding a high ranking position for long. Myself and you have long predicted Kuma will achieve the role of being alpha female in the future, and in my opinion the next five or so years will be huge for her without any other real candidates.

Interesting to hear Liwali is larger than Sudi, you would think much the opposite genetic wise . Sudi has the benefit of having two large parents (Shiba and Shikamoo), whereas Liwali's maternal side are on the smaller side. Considering they're close in age, it's possible Liwali's just had a growth spurt, Sudi should catch up soon.

Also, any word on Fumo? At eleven, he's surely making his beginnings in the male hierarchy.

No specific reason was mentioned for the drop in Naomi’s status, but like you say, her close ties to Shiba’s family seems likely; combined with the fact that since Niambi hit the juvenile stage, Naomi has neither the benefits an infant brings nor that of adult (male) offspring. The original plan was for her and Kuma to come off contraception this year, but that’s been postponed due to the disruption of demolishing Serpentaria. As such, the next few years will be crucial for Naomi. If she’s successful in producing a surviving infant within the next few years (especially a son), she’ll be set for a comfortable 30’s and would be a strong contender for alpha female a decade from now.

Kuma got off to a strong start - a son at 12 years old; and a son at 22 years old. Combined with her size and temperament, I’m still confident we’ll see her become the alpha female. An infant as per above would really cement her ranking imo.

Fumo is very much making inroads in the hierarchy. Last I heard, he was challenging Samaki and has risen above both him and Shabani in the hierachy.

The ranking of the males is currently:

1) Sule
2) Shikamoo
3) Furahi
4) Fumo
5) Samaki
6) Shabani
7) Liwali
8) Sudi

Considering Lisa’s ranking, it’s reasonable to believe Liwali will surpass Samaki and Shikamoo within the next year imo.

I too was surprised at Sudi and Liwali’s size. Liwali clearly takes after his paternal side; similar to how Furahi (the son of a large female) is only medium sized for a male, like Lubutu.

Hamilton Zoo Update

Update from my visit (29/10/2024):

Spoiler: Hamilton Zoo’s Troop (2024)

1.0 Lucifer (16/06/1988) Mike x Lucy
1.0 Luka (28/02/1993) Mike x Lucy

0.1 Lucy (24/11/1975) Bobby x Lulu
0.1 Sanda (10/04/1985) Peter x Fimi
0.1 Chiku (15/02/2016) Luka x Sanda
0.1 Kendi (17/12/2020) Unknown x Sanda

I saw the chimpanzees inside the night house and out on exhibit; and both times, the social groupings were similar:

In the night house, Sanda was sitting in one of the nests; while Luka and Chiku slept on the adjacent ledge. Kendi was in a playful mood and wrestled with first Chiku and then Luka, before climbing into Sanda’s nest. Whilst this was going on, Lucy was sleeping on the ledge on the opposite side of the night house (i.e. as far away from the others as possible). I couldn’t see Lucifer, but one of the slides to the outdoor exhibit had just been opened (below Lucy), so I assume he’d just gone outside.

In the exhibit, Sanda and Chiku sat on the top level of the climbing tower; while Kenzi transferred between the two of them. Luka slept on the next level down, which is his favourite spot. Lucy slept in the grass some distance away, while Lucifer sat besides her.

It was evident from my May visit (when I watched them at a scatter feed) that Lucy had retained her status as the highest ranking female. While it’s possible that Lucy, who turns 49 next month, is avoiding the hustle and bustle that comes from the younger chimps; my assessment is she’s content with her own company and that of her immediate family. Though Chiku and Kendi are her grandaughters; in chimpanzee society, the concept of the family unit is based around the mother and her offspring i.e. Chiku and Kendi are Sanda’s offspring; Lucifer and Luka are Lucy’s offspring.

Historically, Lucy has been closer to Luka. He was the last of her offspring, so there were no subsequent infants to take away her focus from him; as he did from Lucifer, who was five when Luka was born. At Auckland Zoo, the chimpanzees were even housed in pairs overnight: Mike and Lucifer; Lucy and Luka; Suzie and Sally (with the groupings obviously dictated by the need to seperate the two handraised females overnight; and keeping Lucy with her intially dependant offspring). Lucy was still highly supportive of Luka into the mid-2010’s; so much so, that Sanda initially showed a preference for Lucifer. From what I’ve seen, the birth of Chiku bonded Luka and Sanda, with them rarely seen apart on my visits. Luka is an exceptional father and gives both his offspring a lot of time. This no doubt leaves Lucifer as an outsider; though as detailed, he spends a lot of his time with Lucy, which is not atypical of male chimpanzees, who maintain lifelong bonds with their mother.

It’s been great to see Chiku and Kendi forging a strong bond on recent visits. Going back a year, certainly two years ago and it was more common to see each of them with one of the adults. It’s not hard to imagine a new infant from Sanda would further cement the sister’s bond, as Sanda’s time becomes preoccupied by their new sibling. Kendi turns four in December, so it’s not hard to imagine Sanda delivering another infant next year. I didn’t get chance to confirm whether she’s off contraception yet; but struggle to foresee why a breeding recommendation wouldn’t be given, considering her genetic value and the passing of her brother at Monarto.

Upcoming Transfer: Rockhampton to Sydney

Leakey and Mzuri transfer to Sydney Zoo next week:

0.1 Leakey (30/12/1994) Imported 2015
0.1 Mzuri (08/12/2021) Alon x Leakey

From socials:

Farewell and good luck, Leakey and Mzuri!

Chimpanzee mum, Leakey, and her youngest daughter, Mzuri, will be moving to their wonderful new home at Sydney Zoo next week.

Rockhampton Zoo's team leader of exotic mammals and birds will be travelling with them to help ensure they settle in well on arrival.

 

[Tiger91]

Exciting times ahead for chimps with some movement about to happen.

Definitely. Sydney Zoo will be gaining a genetically valuable female of reproductive age, who’s also successfully raised two offspring. This will stand them in the best stead of starting a breeding troop. It’s also beneficial from a genetic standpoint to re-pair Alon and Leakey after two offspring.

I’ll admit my initial hopes for Sydney Zoo were for them to take a splinter off group from Taronga (maybe even bachelor males); but the imports from Europe, as well as Rockhampton’s, have opened up possibilities for exchange.

Assuming the region continues to follow the female dispersal pattern, there’s be many more transfers over the next 5-10 years as the female juveniles and infants mature.

Id love to see Taronga seperate out all the males, bring in some new ones from overseas. Then build a facility at Dubbo for chimps, for a bachelor group. Dubbo desperately needs some new species, and is stagnating something terribly of late, they have plenty of space that can be better utilized instead of the current filler. And it would give the zoo a lively and fun exhibit, that is a draw card species.

And it would give the zoo a lively and fun exhibit, that is a draw card species.

It amazes me that Dubbo are the only main zoo/open range zoo in the region without a great ape species. In the 1990’s, they were planning to hold a bachelor troop of chimpanzees, which I assume was to facilitate the introduction of Snowy (juvenile male imported from Taronga Zoo in 1986) to the colony, which took close to six years and required the removal of males - Danny, Sonny and Mervin. Sonny died unexpectedly and Danny and Mervin were exported to India in 1992, along with a handful of females.

The Rockhampton/Sydney transfers will provide interesting insight into introductions of unrelated chimpanzees. The introduction of unrelated intact adult males are the most challenging; but transfers of castrated males have had mixed success (the greatest opposition being from a female, who regarded the castrated male as competition). The introduction of a juvenile (along with its mother) to a troop contained an intact (albeit docile) adult male will also be a pioneering introduction.

Taronga’s current community is as follows:

1.0 Shabani (14/09/1994) Monte x Shiba
1.0 Samaki (27/11/2001) Lubutu x Shiba
1.0 Furahi (28/02/2003) Lubutu x Kuma

0.1 Lemba (23/05/2023) Unknown x Lisa
0.1 Cekiri (29/07/2023) Unknown x Ceres

One theoretical option could be to transfer out the eight adult and adolescent males and attempt to integrate an adult female and her juvenile/adolescent male offspring. These incoming males would have the protection of their mother against the community, who in turn should effectively protect the infants/juveniles (Safiri, Niambi, Lemba and Cekiri).

All things considered, I believe it’s more likely we’ll see a continuation of the female dispersal trend. There’s been a wave of females births regionally over the past decade, ensuring countless opportunities for exchange as they mature.

Taronga are in a position where they need to bring in new males. All Of there males, except for shabani descend from Lubutu. And shabani is related to Samaki and Sudi, the males that are breeding more recently, via their mother Shiba, and both those males are sons or grandsons of Lubutu.
Even if they keep breeding Naomi and Ceres, the male offspring will undoubtedly descend from lubutu as well.
At least with the females there is more genetic variation. The younger females can be retained giving Taronga a decent amount of breeding females moving forward. While a troop of 9 males in a bachelor troop at western plains would be a good number for a nice sized exhibit that would be engaging to watch.

I’d be surprised if we saw any breeding from Shiba’s line anytime soon. Her son Samaki (2001) sired Liwali (2014) and Cebele (2017-2023); but is now low ranking in the hierarchy and the current alpha male, Sule (2008), has sired the last four surviving infants: Safiri (2019), Niambi (2020), Lemba (2023) and Cekiri (2023).

On that note, the Biddy (mother of Spitter; grandmother of Sacha) line is becoming very well represented regionally:

Sandali (1996) and Enzi (2015) are the only reproductive males in Monarto’s troop.

Sule (2008) and Shikamoo (2003) are high ranking in Taronga’s troop, with a total of six surviving offspring between them.

Bakari (2012) and Akida (2021) comprise 50% of Wellington’s males. Bakari is a strong contender for the alpha male role in the future.

With the above in mind, it’d be good to see Alexis (1998) in Wellington Zoo’s troop breed with Malika (2010). He’s her best genetic match and the next upcoming males are her half-brothers. Alexis, his 43 year old mother Cara and his juvenile son Akida are the only surviving descendants of Bessie (1950-2011).

Hamilton's Chiku and Kendi seem likely to transfer to Wellington, in my opinion. It will be interesting to see if any of the females who will eventually disperse from Australia will end up at Hamilton Zoo.

I wonder if Monarto Zoo intend to transfer out or retain Zuri - news hasn't been clear on that front, and she would need to have someone transfer out with her.

Monarto were initially planning to retain Zuri, but now the only reproductive males in the troop are her father and full brother, there’s little justification for keeping her in this troop. Her mother has two additional offspring to provide her with support, in addition to being the alpha female and of breeding age. Her youngest daughter Zola may have been sired by Tsotsi, which if so would make her a match for Sandali and a better match for Enzi than a full sibling.

Due to the demographics of Wellington’s troop, I’d expect to see any incoming females arrive with support (i.e. sisters). Wellington’s females are: Sally (alpha female, mother of two sons); Cara (mother of the alpha male); Samantha, Keza and Malika (mother and daughters trio). It would be an imposing experience for any female assimilating into this troop without support.

Wellington Zoo Update

Keza has underdone a medical assessment which has identified she has high blood pressure, which they will be treating her for. It’s great to see the zoo being so proactive in addressing this given the prevalence of heart issues in great apes.

With this in mind, we can assume Keza is back on contraception and will not be breeding until her condition has been successfully managed. Keza is 26 years old and has a 10 year old son, Kitwe.

Due to the ages (39-43 years) of the three older females in the troop (one of which hasn’t bred for 21 years; one of which hasn’t bred for 14 years), it seems likely the next to breed will be 14 year old Malika. As I mentioned in a previous post, it’s an excellent opportunity while Alexis is the alpha male and the most likely candidate to sire her infant.
From socials:

Last Saturday Keza the Chimpanzee was anaesthetised in the Chimp house so our team from Te Kōhanga, assisted by a specialist human Cardiology team from Wellington Hospital, could evaluate her heart health.

Over the past few months, our Animal Care team has noticed that Keza had some swelling in her feet that didn't resolve over time. Because this can be a sign of problems with the heart, our Vet team decided to bring in a cardiologist to check Keza’s heart.

Thanks to our expert Animal Care team’s planning, and training Keza for voluntary injection of her anaesthetic drugs, the procedure went very smoothly. The cardiology team performed an echocardiogram and electrocardiogram and found evidence of some thickening of the heart walls associated with hypertension (increased blood pressure). ‍

These diagnostics are essential for creating a tailored treatment plan for Keza. Our vets have prescribed a blood pressure medication called spironolactone, and the Animal Care team are working on training Keza for voluntary blood pressure monitoring going forward.

Taronga Zoo Update

Update from my visits (18/11/2024 and 20/11/2024):

I made two very enjoyable visits to Taronga’s chimpanzee community. The second visit was with @steveroberts and we came at a particularly exciting time. The community was inside the meshed exhibit and Shikamoo and Sudi were fishing for food right by the window. Shikamoo spent a lot of time with his two sons when they were infants and juveniles, so it was nice to see them sharing a close moment a decade on.

Several males began displaying. The crowd was delighted, but the female chimpanzees less so. Ceres picked up Cekiri and ran to the nearest corner, where she began screaming. Safiri also ran around screaming, though she appeared more excited than fearful. I’ve heard numerous accounts of Ceres’ strong maternal behaviour and her protectiveness of Cekiri was certainly evident, which was great to see.

There will be no breeding for the next year at least. All viable females are on contraception. The reason for this is once the demolition of Serpentaria is complete, they’ll be building an animal hospital on this site, which has the potential to be disruptive.

Sembe will not be breeding at Taronga. The current plan is to transfer her out long term. No information on where this might be, but I would say Sydney Zoo and Rockhampton Zoo are the most likely given her relatedness to other troops in the region; and the fact she’d likely be transferring alone.

Kamili has made significant inroads in the hierarchy, despite her absence of family support. Lisa and Kuma are also high ranking in the female hierarchy; with Shiba having dropped considerably in ranking.

Samaki and Kuma:



———————————————

My comments:

It appears future breeding will be undertaken with Ceres, Kuma and Naomi:

The three eldest females (Lisa, aged 45 years; Sacha, aged 44 years; and Shiba, aged 43 years) are well past their reproductive prime and have sufficient representation - both genetically and within Taronga’s community.

Shona is sterilised; Kamili has not succeeded in rearing offspring; and Sembe will not be breeding at Taronga.

If we’re to assume breeding resumes 2026, the best plan appears to be to allow Kuma and Naomi to breed in 2026; with Ceres then breeding circa 2028, allowing Cekiri to be of sufficient age to allow Ceres to focus on her newborn, but taking into account Ceres ie now 34 years of age and getting on in years. It wouldn’t be surprising to see Naomi allowed to have to have a total of four offspring in the community, with any sons retained to support her.

Long term, Taronga would surely opt to import more females. A decade from now would tie in nicely with Ceres and Kuma retiring from breeding; and Safiri, Cekiri and Lemba reaching dispersal age.

I saw a similar thing with Ceres, and it in fact took place in the meshed exhibit too. A debacle was thrown I believe by Kamili and then aggravated by the males. Ceres, who was initially being groomed by Samaki picked up Cebeli and bolted up to the top of the enclosure near the dens where she cowered and screamed for a while before being confronted by Lisa. She seems to be quite avert to any drama within the troop, as do most of the females. In her later years, Spitter would round up the kids to keep them out of harms way.

It's also not surprising to hear Sembe won't be breeding at Taronga. She is related to all of Taronga's males so this isn't possible unless a new male is acquired (very unlikely). When Capri eventually transfers out of Rockhampton (in maybe five or so years time), Sembe could be transferred up there as they'd technically only have a single breeding female by then; the new female soon arriving from overseas.

Kuma and Naomi have also shared a relatively close bond as of late so breeding them together in 2027 ish (once the wildlife hospital is completed) would be nice. Considering Ceres's age it may be best to bred her then to allow her to have another offspring if need be.

Good to have an update on Taronga's community. I have many fond memories of this troop who seem to be the heart and soul of Taronga. Was very sad to hear Spitter had passed a few years back. She definitely lived up to her name with her feisty and protective attitude but mellowed out as time passed. She was a wonder with the kids, she seemed to love her grandchildren a lot and was always one to stand up for them in times of need, a unique trait of hers.

I haven't been in touch with the chimp troop that much since I left, Ceres and Naomi would be new females correct? I heard about an import but I seem to remember the females didn't settle in well so I perhaps had falsely assumed they'd been sent elsewhere as a result.
