With the European groups I'm somewhat familiar with it does seem like they have quite a unique structure in the Copenhagen Zoo! And yes, Carl was the alpha, he passed away some years ago, though I'm not sure from what.
Him, Yoran, Cindy and Marti arrived together from a lab in the Netherlands. On the original list Changa and Maadili are also mentioned, Carl was also their father. After fathering so many children, the zoo had actually wanted him to step down from the alpha spot as they wanted Yoran to have some kids as well for more gene-diversity. They tried to see if they could lower Carl's testosterone levels, but it was unsuccesful and they concluded that Yoran probably wasn't interested/made for the spot. Him and Carl had a nice deal, as one part from
the article written about it says translated: Carl gets ladies, Yoran gets food (Yoran is quite chubby and a very well mannered and sweet chimp, I definitely have a soft spot for him). Yoran did try and breed with the females back when Carl was around and he is missing one finger on each of his hands because of it, as they were bitten of by Carl as he had been seeking forgiveness from him. When Carl died it seems it didn't take long for his son Nje to step up. I have my fingers crossed that Marti's new baby might be Yoran's, but seems like the chances for that while possible might be slim and I have heard more people pointing towards Senko.
Other chimps who are no longer in Copenhagen are Maadili, Djema, Jenny and Changa. As mentioned in an earlier reply on this thread both Jenny and Djema passed away in 2023, they were both in their early 40s.
Maadili was moved to Edinburgh Zoo as he had started getting aggressive with the youngsters and females in the group, sadly the integration seemed to not go well and they ended up euthanizing him, this was in late 2021 and he had been living around a year all by himself.
Changa was moved to Leipzig where she still lives and she actually had a baby quite recently who has been confirmed to be a boy! Even more Carl genes to the world. I'm actually going to Leipzig later this month and I'm hoping to catch a glimpse of her and her young.
Most of the Aalborg Zoo chimpanzees were moved to other zoos.
Maja, Lone and
My to Ostrava Zoo in Turkey,
Sebastian to
Walter Zoo in Switzerland and
Laura to Burgers Zoo in the Netherlands. Dorthe and
Jutta has passed away, not sure how old Dorthe was but Jutta was euthanized due to complication with old age. As far as I know the chimps moved are still alive, I know when they moved they had hoped some of the females would end up having some babies. Someone else who keeps up with those zoos might have a more detailed update on how they're doing today!
From Givskud Naomi and
Ceres were moved to Taronga Zoo in Australia. Ceres has also had a baby, but seems Naomi has had some issues with pregnancies and the babies after giving birth. I'm unsure about where Judy ended up. She was supposed to be moved to Kristiansand Dyreparken in Norway but it seemed there were issues with her transport. Haven't been able to find any other information.
In Odense Zoo Agnete (who was the mother to Svabba and Knaus) has passed away, I think it was age related.
Ricardo tragically died in a drowning accident in 2017, he was 20 years old and had only been at the zoo for a couple of years. The females chimpanzees had been aggressive towards him and to escape he jumped into the moat. A very sad story, I'm glad EAZA no longer recommends having moats for newer enclosures.

Sorry this ended up a bit lengthy, I'm very happy to hear there's some interrest for the Danish and ex-Danish chimpanzees!
