The reasons the Indonesians are not breeding Rosa is frustrating specialists. The Indonesian's philosophy is really just do nothing and whatever happens is acceptable. Rosa is people bonded and doesn’t like other rhinos, so they are keeping her separate. But since the rhinos are solitary anyway, only coming together for breeding, there is no reason for complete separation even during that critical time. She absolutely needs to have a calf soon, for her sake and the species sake, but there is no sense of urgency at the facility. Again, risks and intervention need to be taken, and the reserve’s inactions are tiring specialists. They won’t breed her with Andalas since he’s been paired up with Ratu (who they are also not breeding anymore and letting her nurse her grown calf, who is now larger than her). Doing this for genetic reasons is moot at this point since so few breedable animals are left and new calves are needed immediately. They also have the option to acquire a new male from the wild/reserve to pair up with her, but there doesn’t seem to be much, if any, movement on this. There is also an unrelated captive male in Malaysia that was supposed to come to Cincinnati to breed with Suci (the Malaysians waited too long to send him though, so everyone lost out on the opportunity to breed Suci before she passed away), but the two countries will likely not cooperate on anything. The last I heard was that they are contemplating performing AI on her, but how long that will take and from which male they may chose I do not know. With Sumatran rhinos having complicated reproductive science, it is unknown how AI attempts will work.
Again, if the proper conditions for Harry can be met, it is possible he could still leave sooner (like next year) than later. Just to be safe, I would still recommend anyone who wants to see him to go before it gets too cold in late autumn, just in case he does leave sooner.
