North American Asian and African Elephant Populations: Discussion and Speculation

https://www.washingtonpost.com/nation/2024/08/30/pregnant-elephants-columbus-zoo/

Just posting this here, as I hadn't seen the details/comments stated in this article in other releases. This article quotes the elephant manager explicitly stating that Rudy at Columbus Zoo is not currently pregnant. I would obviously take this with a grain of salt, but it is probably the most confirmation I've seen on the subject from officials thus far.


It’s still early in the game! Rudy is indeed at the tail’s end for a first calf but it’s not too late yet. Johnson should be there longer than Sabu so he has more time to catch her at the right time of the cycle.

Keep in mind the cow may be willing to allow the bull to mate but it doesn’t mean she is ready to ovulate. As in the eggs are at the right time for fertilization.

Johnson is the perfect bull to have right now as well. He's quite the super bull with a stunning dozen calves sired (11 of those being daughters!)
  • 0.1 Nellie (Johnson x Natasha)
  • 0.1 Hannah (Johnson x Lily)
  • 0.1 Gigi (Johnson x Emily)
  • 0.1 Anna May (Johnson x Opal)
  • 0.1 Rose (Johnson x Natasha)
  • 0.1 Luna (Johnson x Lily)
  • 1.0 Onyx (Johnson x Opal)
  • 0.1 Sunita (Johnson x Natasha)
  • 0.1 Imke (Johnson x Lily)
  • 0.1 Maya (Johnson x Emily)
  • 0.1 Abigail (Johnson x Lily)
  • 0.1 Olivia (Johnson x Opal)
Introductions began between Rudy, Sunny and Johnson began as early as mid-July, so they very well could be sharing space by now. Given his record, it wouldn't surprise me at all if he succeeded with Rudy (given she isn't pregnant already).

Yes. I agree the number of calves especially females that Johnson has sired is overwhelming. On the other hand he is a proven bull so he can get it done when Sabu hasn’t. One or two more Johnson calves (especially female) wouldn’t hurt especially if African Lion Country doesn’t release their females by him. There is only one male so that really limits the gene pool outside of ALS.

maybe Emmen should petition for him with all of those females. Whatever they are feeding their bulls for all of the boy sperm shouldn’t kill Johnson’s female sperm. Ha ha.
 
Rumbling in Omaha that they would like to expand elephant exhibit already, and build another barn for a potential bachelor holding. Suspected was rumor, however was on a survey sent out by Omaha Zoo Foundation to foundation supporters this week.
I don’t know how much space they have to expand around/behind current exhibit. Will be interesting to see what unfolds.

It would be in Omaha's best interest to expand their elephant exhibit for future breeding and housing any bulls born their.

An expansion would be 100% the perfect path for Omaha.
It should be the goal of every breeding facility to have the capacity for multiple adult bulls and bachelor holding. Omaha especially if they wish to continue breeding at the rate they have been. I'm unsure of their current capacity, but surely their goal is to produce another 5 calves within the next 3-4 years.
 
How many acres do the elephants utilize at Omaha zoo? Barn?

maybe they can purchase some land outside of the city like the Columbus zoo does for some of their animals (Wildlands) and create a bachelor herd out there. If they are landlocked like so many zoos.

Omaha's Henry Doorly Zoo already has an offsite safari park - The Lee G. Simmons Conservation Park and Wildlife Safari.

The Columbus Zoo's offsite safari park is called The Wilds, not "Wildlands".

And yes, Omaha's Henry Doorly Zoo is landlocked. They'd have to tear down parts of the current zoo in order to expand the elephant exhibit.

Wouldn't surprise me if they'd prioritize an elephant expansion over other existing exhibits. They are a huge draw for the zoo and have a species with the most potential for a long-term successful breeding program.

oops. Thank you for the correction and further information.
 
So, when's Kandula (the young male from D.C. that now lives in Oklahoma City Zoo) going to be able to prove himself?

That being said, he does have a lot of half siblings so maybe there's not a huge rush.
He currently does not have a breeding reccomendation afaik. He could be perfectly able to breed naturally but he isn't a priority of the SSP at the moment so he's probably not being put with the females while they cycle. Likely due to his numerous siblings, and the fact that the other young bull at the facility, Bowie, is comparatively much more valuable.

Yeah I realized he's not super valuable when I looked at his family tree, especially seeing that he's closely related to Johnson (the one heading to Columbus)

He is his wildborn mother's only offspring, so he does have that going for him. It's likely he'll be placed in a breeding situation at some point down the line, especially at OKC. It's becoming more and more common for facilities to house two intended breeding bulls (Houston, Columbus, etc), so its extremely likely he will fill the niche inevitably left by Rex in not too many years.
 
Apparently the PAWS Sanctuary's 29 year old bull elephant Nicholas weighs 17,000 pounds. That would probably make him the largest elephant of either species in the Americas, unless I am forgetting another larger bull.

I haven't seen any photos, and this is pure speculation - but I wouldn't be wildly surprised if that's a weight issue as opposed to him naturally being that large.

It is almost certainly a weight issue. The largest bull I know of, Hank, is 15,000. I can't find a source on being 17,000, but if true he is overweight.
 
To be fair, there are a handful of Asian bulls that do hit great sizes without being particularly overweight. The stand out example that comes to mind at the moment would be Thisiam at the Knies Kinderzoo in Switzerland. He is over 17,000 pounds, and in reasonably good body condition. However that said, he’s also just a massive bull in general, very tall and well-built.

in the case of most of the very heavy animals in the states though, Prince, Hank, and the like, their weights come down purely to being obese.
