Two Francois' leaf monkey infants were recently born. Currently, there are 13 individuals (6.5.2) at Zoorasia. In total, 33 individuals (17.14.2) are kept at six facilities across Japan. This species is managed under the JSMP.

Can you list the numbers as per the 6 participating zoos in the JSMP/JAZA?

Does JAZA work together with PR of China on joint management of Francois leaf monkeys?
 
During my visit a few days ago to the Japan Monkey Center, I saw some keepers holding a baby langur. Due to my lack of knowledge, I couldn't identify the species, but looking at photos now and the list of species at the center, I'm inclined to think it was a Francois' leaf monkey . I don't know if this young animal is among those counted here.

With how common it is in Japan, I thought it would be common in zoos in Germany. Turns out, Berlin Tierpark is the only place in the country to keep them.
 
Zoorasia currently has seven proboscis monkeys (3 males and 4 females). They were previously split into three groups, but have recently been reorganized into three new ones. Kinship is no longer prioritized, so most pairs are very closely related. The last death at Zoorasia occurred eight years ago, and since then, breeding has continued under the surviving founders and their descendants, resulting in a population with high relatedness. While Zoorasia is not as overwhelmingly successful as Chimelong, it is likely the only zoo in a temperate region that has successfully kept this species so far. In recent years, there have even been days in mid-December when the monkeys go outside at noon. I hope Zoorasia can continue keeping them in the future and that imports from Indonesia will be possible, though politics are likely to make such imports take a long time.

Be nice if the Zoorasia management can bring in an unrelated male from Indonesia (Surabaya ... with their large group of 30-40 proboscis monkeys comes to mind!

Although all the founders originated from Surabaya Zoo, four haplotypes were identified among the five founders, suggesting that no severe inbreeding has occurred in the Surabaya population. Therefore, importing additional individuals from Surabaya Zoo should not pose any major genetic problems.

Moreover, haplotype analysis revealed that the haplotypes found in Zoorasia individuals are genetically distinct from those in Malaysia. Thus, breeding should preferably be conducted among individuals of Indonesian origin. Since most captive individuals are indeed from Indonesia, this is not a major concern, but I thought it was an interesting point to share.
