ZSL London Zoo ZSL London Zoo News 2019

That is heartbreaking news about Kumbuka. I felt I had a special connection with him while he was at Paignton (I'm sure I wasn't the only one) and he recognised me when I visited him twice at ZSL. I can't believe it :(
Isn't it strange now London zoo have lost 3 male gorillas in not that many years, I don't know, only worked with big cats mainly, but becomes a bit weird when all the females seem to thrive?
 
Yes, I think so. I checked with our keepers today, and they are annoyed they did not take photos of the signs/posters, which were up at the exit of the aquarium. I am told that they certainly gave the impression to the general visitor that the aquarium was being relocated, and made no mention of its closure. If Tim took some pics it would be interesting to see their content, as it does seem to be an attempt at 'spin'. I guess if they quietly cease referring to the old aquarium the general visitor, looking at a new exhibit, will never know it existed and not be in a position to make a comparison. Not quite erasing history, but still a pity as I think the zoo story, the journey and the achievements should be embraced and not allowed to die too.
It was all pretty clear. I wrote an article for the Bartlett Society to record its final days.
 
Likely to maybe referring to the signs which have been at the entrance/exit as shown in the photos below, which talks about the future in terms of the now open aquarium at Whipsnade and the future corals exhibit in BUGS some point next year.

Includes the inexcusable cropping out of the King in a picture supposedly showing the King and Queen! It replaced a sign that was correct.
 
Very sad news, Kumbuka has tragically died.

Statement from ZSL: We know that many of our Fellows have strong relationships with our animals, especially our big personalities, and like to keep up to date with their news.

Unfortunately on this occasion we have some sad news to share. Kumbuka, ZSL London Zoo’s silverback gorilla passed away on Friday 25 October.

Working closely with Kumbuka every day, our keepers had noticed that he was unwell – he was uncharacteristically off his food and drink, appearing lethargic and not as eager to play with his family troop as usual.

Following close observation from the veterinary team, the decision was made to give Kumbuka a general anaesthetic so that the team could get a better understanding of what was making him unwell.

Once anaesthetised, and with the support of specialist doctors from University College Hospital and Guys and St Thomas’ in London, our vets could see that Kumbuka had an infection which required surgery to further investigate. Sadly this revealed that the infection was severe and widespread, and that the kindest, and only, option was to not bring him round from the anaesthesia.

We will all remember Kumbuka as a larger than life character, a devoted father of two and proud leader of ZSL London Zoo’s troop. He will be sorely missed by those who worked with him every day and by our many visitors who were so impressed by his sheer presence – we’ll look back fondly on our charismatic, gentle giant.

Our team will now focus on ensuring the females and infants, all of whom appear healthy and well, remain settled over the next few days.


I didn't receive this; they are able to email me to remind me to pay my Fellows fee but not, apparently, with Fellows news. I found out through Facebook.

Perhaps has something to do with the background of available males, which is more restricted than females.
 
Correct me if I am wrong anyone, but haven't we had more success with orangs anyhow? And went out of them because they look 'sad' for the general visitor? I seem to remember reading something along those lines.

Orangs were previously successful; visitor perceptions of 'sadness' are not reflective of success.
 
I’ve said it before and I’ll say it again, London Zoo’s gorillas have experienced more tragedy than the Kennedy’s.

Kumbuka was an impressive male I had the privilege of visiting him last time I was in London and I’m shocked to hear of his death at a young age.

With his two young offspring in the troop; let’s hope we don’t have a repeat of last time, where a new adult male was introduced before the incumbent offspring matured. The female offspring is five years old; the male four, so surely the troop can cope without a silverback for three years. After which the young male (aged seven) can leave the troop; and the young female (aged eight) can be safely introduced to the new male.

I was surprised to learn a few years ago, one of Kumbuka’s ‘wives’ was his grandmother, Zaire:

Jambo/Nandi > Zaire > Kamili > Kumbuka
 
I doubt whether ZSL would want to consider any other apes instead of gorillas because the exhibit would need so much remodelling. But I wonder if either of the breeding females might be pregnant again. It would be a good thing if Kumbuka could have another son or daughter posthumously, but it would postpone and complicate the eventual introduction of a new male.

It might have been pretty clear to you, but apparently visitors (who would not be members of the Bartett Society, I guess) were leaving with a different impression.

Yes they probably were but I responding to what you said and I am sure you would have realised what was going on if you had been there to read the signs. General visitor would have thought freshwater fish going to Whipsnade and Marine fish and corals to BUGS and not been aware of the massive downsize but it was very clear that the current aquarium was closing and, indeed, the first section had already been closed for some time. Equally, though, the general visitor would not have realised they were walking past dozens of boarded over exhibits unless they had visited in the 1980s.

It seems almost insensitive to start discussing the future after Kumbuka's shock death, but of course the future needs to be faced. They may indeed decide not to replace him immediately, to safeguard the two youngsters, and even more so if either of the breeding females are currently pregnant. If they play their cards right they could now keep Mjukuu's daughter as an additional future breeder. As far as a male is concerned, the problem with not adding a new one over a protracted period is the females may become stressed. Zaire in particular has acted very negatively(hair plucking etc) in the past to a silverback death. The best choice might be either an older quiet male, or a young subadult e.g. 8 years old or so, that wouldn't be big and strong enough to harm the youngsters and could grow into the group. Not a feisty young silverback. Either way its not ideal but I have no idea at present what they will do now.

They were almost too successful. Many young were bred. The problems were seen as visitor perception of them, coupled with being 'labour intensive' as far as housing them i.e. could not be kept as a single group. I doubt they will ever keep them again.

How receptive would the females be to an unrelated subadult male though? Any male not so old as to pose a threat (i.e. less than 10) wouldn’t have the presence to assert authority over the females. I don’t know the gorillas at London very well but I think you mentioned once Zaire is quite a strong willed female and that one of the previous silverbacks (Bobby?) was a small, weak male who had little control over the females.

Are the females off contraception? Mjuuku is a young female, who last gave birth five years ago; so I’d have expected her to have given birth by now if she wasn’t on contraception.

In that respect then, would Pertinax from Paignton work?

This is the problem. Its true a young male would probably not be so well received by the adult females as a silverback- but he would be far less risky as an introduction to the two juveniles. Its a difficult choice as to which path they might take. (Its correct Bobby was not very dominant, but he had a very poor background.) I don't know the situation re contraception.

Surely the youngsters are old enough that the females should be ready to conceive again that the youngster are not likely to be killed by a male to breed with the females, but they may not be independent enough to get out of the way when the male mates the female and might cause injury to youngsters.

I suppose it all hinges on if the females are pregnant so nothing if going to happen for at least a year.

Yes they're old enough to be safe from infanticide, but he might still take a dislike and try to eject them from the group, or bully them badly. Or he might accept them with no trouble... just depends on the individual and unfortunately only when its tried would the result be known.

The risk of a new male killing the youngsters just simply isn't worth taking, both from the group and ZSL point of view. They will have to stay without a male for a while and if one of the females is pregnant, even longer.
Incidentally, are there any plans to move the male tiger on? I hope so, as killing another female would be disastrous publicity!
