Yes. Tombo, Tonyi and Kura were all pure Krugeri (hence Amira was too)
Don't know about Mogo's line. Would probably have to get an international studbook to find that out
Dreamworld - Tiger Cubs
It doesn't seem to have been mentioned on here already but on 24/01/2018, Nika gave birth to 0.2 cubs named Melati and Mya. The father is Raja and this is their third litter together:

Hybrids again.![]()
I agree it's a shame they're stocking up on hybrids again.
Cats featured (pictured) were Lion, Sumatran Tiger, Snow Leopard, Jaguar (black and spotted), Cheetah, Puma, Leopard Cat, Serval, Ocelot, Bobcat, Fishing Cat, Asian Golden Cat, and Caracal.
Sigh.
Just a random post:
While unpacking boxes I came across my old Melbourne Zoo guidebook from 1992.
Cats featured (pictured) were Lion, Sumatran Tiger, Snow Leopard, Jaguar (black and spotted), Cheetah, Puma, Leopard Cat, Serval, Ocelot, Bobcat, Fishing Cat, Asian Golden Cat, and Caracal.
Sigh.
I'm sure I remember black leopards there a few years later, and then by the 2000's they had Persian leopard and indochinese clouded leopard also.
Also a very large primate collection around this time.
Melbourne definitely had black leopards. I can't tell you when from but definitely into the '70's and the '80's. One was "Trooper Pardus", the mascot of an Australian army cavalry regiment.Are you sure you don't mean the melanistic jaguar?
The reason is likely that the Sumatran tigers are part of a managed program. Despite the way zoo PR spins it, the idea behind a managed breeding program is not actually to necessarily breed MORE tigers but just to MAINTAIN tigers. Thats especially true for a subspecies with a low genetic founder base, such as is the case with Sumatran tigers. Thats why zoos so regularly leave breeding until right at the last moment when the animals are near-post reproductive. The less generations of tigers that tick over, the slower the rate of inbreeding and the longer the subspecies survives. As a result many zoos in Australia who might want to acquire or breed Sumatran tigers might actually find there are none immediately available and no breeding recommendations on the horizon either.
Could Dreamworld just breed surplus of their Sumatrans for display? Probably, but likewise they could do exactly what they are doing: Make a responsible contribution to the ZAA's Sumatran breeding program and breed additional hybrid tigers, at will, for their own commercial interests. Interests that I might add probably make a much larger contribution to tiger conservation that most of the other zoos combined.
But if I may suggest another angle here, my own personal opinion: My attitude towards hybrids has come full circle over the years, shifting from an original purist stance that they represent nothing more than space wastage, to actually having concern that we are going to phase out hybrids from zoos at the expense of captive genetic diversity.
Take leopards for example. There was a time when a leopard was a leopard and hybrids or leopards of unknown ancestry constituted most of the captive population of leopards in the world. Then we shifted into a purist stance and started only keeping pure bred leopards. But we didn't actually have purebreds of every single subspecies of leopard, and of those we did have we had only a very small number of founders. Meanwhile leopards continue to go extinct in the wild. Fast forward to 60 years from now - The leopard is extinct in the wild. What we have is a few separate breeding programs for lets say, five pure leopard subspecies. But each breeding program is now suffering form inbreeding depression due to a low genetic founder base. The only way we can save the leopard is to start introducing the odd purebred animal of another subspecies into the others gene pool.
Now lets imagine that at this time we actually had a 6th breeding program. One of genetically vigorous hybrids. Instead of mixing those five purebred (but inbred) populations with each other, we can introduce a bit of healthy hybrid into each population. I dare say, the hybrids are not just genetically healthier, but also likely to be carrying at least some genes of of the purebred species they are being bred back into and thus technically keeping the lines just that little bit purer. In either hypothetical we are forced to hybridise. But its with the hybrids that the leopard is better off - both as a subpecies AND a species (and I won't even go into the risk of losing melanistic genes through hybrid phase-out).
My concern is that we are throwing the baby out with the bathwater. I fear we are phasing-out hybrids under some false pretence that zoos can preserve purebreds in the long term. Most zoo species actually don't have the genetic diversity to maintain themselves in the long term and you're kidding yourself if you think many more will filter in from the wild before extinction occurs. One only needs to look a Sumatran rhinos, Andean tapirs, Indian tigers. Good luck convincing the politicians of their range countries to share any of those last specimens with the world's zoos.This is despite them dwindling to the brink of extinction in the wild. Or take the northern white rhinos. We deliberately phased out some hybrid-whites only to a decade or so later attempt to start hybridising figuring something is better than nothing.
I say value and manage and the hybrid tigers as an distinct and isolated breeding program just as you do the purebreds. When the Indian tiger goes extinct in the wild, we might just appreciate those mostly-indian hybrids a lot more than we do now.
