@Kifaru Bwana, I was using the AZA info on breeding age issues. Won't even argue with you because I know you are extremely well versed in rhinos. If you say 20 is more realistic then I take you at your word and hopefully Sabi gets more time because things don't look good. You are right Tony too was inexperienced but he was tried too because he was more aggressive and assertive than Tom so they hoped the girls would stand for him. The girls preferred Tom to Tony so much so that the zoo ended the experiment after not all that long if I recall right. I'll just keep hoping for white rhino calves in the next year or more likely 2.
@Akula I can help with the orang question too. Budi is to stay as you said and breed. A decision that annoys me to no end. Because they have sat back and waited for Budi to mature enough that Sekali and Ramai will breed with him both girls have lost an entire breeding cycle and thus a critically endangered species has lost two babies. A male was to come up when the trio of youngsters was 8 or so years old but he died shortly before he was to arrive. Since then the plan is to waste reproductive years waiting for Budi to be mature enough the girls will allow him to breed with them. They were trying to breed earlier and Budi and Sekali were getting on ok but she wouldn't allow him to breed. At some point she decided she wanted nothing to do with him. I don't blame the SSP for not replacing Molek when he died because the kids were still so young but once they were older it was just stupid not to. Not only have they lost two babies but Jingga has not had a chance to witness her mother raising a younger sibling which normally would happen. She would get practice in.
Kembali's future is less clear than his big brother. Obviously he has to leave. Sekali is is mom and Ramai is his aunt/cousin and Jingga is his half sister. He is to chill in Toronto until he matures but after that he could go anywhere. I do however have a theory. I believe he has been left to mature in Toronto because he will be Calgary's breeding male when they convert the panda exhibit to an orangutan exhibit. By making him their breeding male it means less border crossings. Not only will Calgary not need a male sent up but Toronto will have to send one less orangutan south. However if they are thinking long term Calgary having a pair that is totally unrelated to Budi, Ramai and Sekali can set up the next generation but that too presents a problem. An unrelated male would be harder to get than a single female for Kembali. Adult male Sumatran orangutans are in short supply. That fact could also mean he's more valuable down south and just a female or two would be brought up and Budi will rotate between Toronto and Calgary as necessary to breed. See Kembali's future is more fuzzy. I would think given the boys age it will become clearer in the next SSP. He will be old enough to breed so if they want him in the US he will probably go. If he doesn't go I would be convinced he is going to Calgary as there is zero point in keeping a much needed potential breeding male in Toronto where hes trapped with females he cannot breed.
Jingga on the other hand does have a transfer recommendation. I wont mention where she is slated to go but the recommendation is nearly two years old so I'm not so sure that is still the same plan. She did not have a breeding recommendation at the time because she still would have been under the minimum breeding age the AZA recommends (14). The next SSP should be out sometime in 2021 so we shall see what that brings for her future. If I had my way I would keep her and send Budi away. While Budi is the youngest son of a founder and long time zoo resident Jingga is a better legacy animal to keep. Her great grandparents are Mias and Abigail who like Puppe were the zoos original orangs and founders. Her grandmother is Chantek the first orangutan born in Canada in August 1975. And her grandfather Dinding holds the distinction of being the longest lasting and most prolific breeding male for the zoo. While her uncle Chedrek was the first second generation orang born at the zoo, mother Ramai is also a second generation and the first second generation orang to reach maturity. Jingga is also the first 3rd generation orang not only born at the zoo but to any of the orangs who descent from the originals. Her baby will be the first 4th generation of the zoos orangutan family tree and I can think of no where else that baby should be born the in Toronto! Plus keeping Jingga is better long term planning. At Ramai's age she will only have one more infant if we are lucky. They will not allow her to breed past 40. Sekali will likely only be allowed to produce 2 more. After that the zoo would be stuck with 2 geriatric females and Budi will likely be sent away to breed elsewhere. By keeping Jingga the zoo would get 25 years of potential breeding so 3-4 infants. They can replace the male as necessary which from a genetics standpoint shouldn't be too hard. Despite being prolific Dinding only has 5 descendants alive in North America (only granddaughter Hesty isn't in Toronto and he does have son Dinar is breeding in Australia). Abigail's line only has 8 living descendants in North America (the other 4 are Remy, Baston, Mila, and Hesty).
Fun side note there is a descendant of Toronto lines living in the wild today. Dinar, son of Dinding and Abigail, moved to Perth Zoo in 2004. There he has sired 4 infants. Eldest son Semeru was released in 2011 but he was bitten by a snake in his sleep and died. His second son Nyaru has faired better. In 2017 he was released to the wild and to the best of my knowledge is still alive and free.
