Hello ZooChatters, As has been done with some other species on this site, I was hoping to see if we can piece together the current captive population of silvery or Javan gibbons (Hylobates moloch) outside of Indonesia. The most recent studbook I have is from 2009, and obviously some things have changed in the last 7 years. Here is the information I have (sorry if it's an overload): Howletts: This population started out with a wild-caught pair who in 2009 had four living offspring and one deceased offspring who reproduced (as of then, the wild-caught female was also still alive). Of their four living offspring, there were two males and two females, all still living at Howletts. Only the younger male had reproduced as of 2009. The deceased offspring, a female, mated with another wild-caught male at Howletts and produced a lone female, who was still living at Howletts then. One of the female offspring at Winnipeg came in and paired with another wild-caught male: they produced 8 (!!) living offspring. They moved to Belfast in 2006 with their sixth and seventh offspring, and had their eighth while at Belfast. The eldest of their eight offspring had offspring of their own prior to 2009. The oldest, a female, had paired with a male from Perth. They had four living offspring. That pair and their three younger offspring moved to Port Lympne in 2007; their eldest, a male, stayed at Howletts. The second oldest of the wild-caught/Winnipeg pair, another female, mated with a male at Howletts; this male is the one offspring from the original Howletts pair that mated, as mentioned before. They produced 3 offspring. The oldest of these (a female) moved to Mogo in 2008; the younger two were still at Howletts. Of offspring 3-5 (who had not mated yet), one (the fourth, and a female) stayed at Howletts after her parents and younger siblings left. An older female (the third) moved to Munich; the fifth, a male, moved to Saint Martin la Plaine, but he went elsewhere as of 2011. In 2008, five additional founders came to Howletts from Indonesia. In 2015, a male and female arrived from Perth; perhaps these were the two youngest offspring of the Perth pair? Port Lympne: As mentioned, a pair from Howletts came here in 2007 along with their three youngest offspring. Munich: A pair of wild-caught individuals (both deceased) produced two living offspring here, two males. One of the males stayed at Munich; the other moved to Port Lympne in 2007. Belfast: As mentioned, the wild/Winnipeg pair and their three youngest offspring were at Belfast as of 2009. Another male and female pair arrived from Howletts and Munich respectively. A female died in 2015. Prague: A male from Munich and a female from Howletts Zlin-Lesna: A female from Munich and a male from Howletts Chester: a male and female from Howletts Curraughs: a male from the United States and a female from Howletts Berlin: a wild-caught pair lived here and had one offspring, a male. This male (Jury) moved to Perth with a female from Winnipeg (Hecla); they have sired at least six offspring. The first went to the Gibbon Conservation Center in California; the second went to Taronga; the third went to Mogo with a female from Howletts; and two were still at Perth. At least one (Owa) but I believe a few more were born between 2009 and 2014. Perth: A wild-caught pair (both deceased now) had one offspring: that offspring, a male, went to Howletts and then later to Port Lympne. Jury & Hecla came in 1992 as mentioned above. Mogo: A male from Perth and a female from Howletts (this pair is related, as both are descended from the Winnipeg pair). They had an offspring in 2015. Taronga: One of the offspring (a female) from Perth lives here; she arrived with a male from the Howletts pair, who died in 2009. I do not know the situation with her or Taronga now. Gibbon Conservation Center: One of the Winnipeg girls was/is here, along with at least one wild-caught male; the two of them have had at least 2 offspring (M) who were still there as of 2009. There was also a third offspring (F) born to the female but with an unknown sire; there were still there at that time. There is at least one female with unknown ancestry that I believe arrived from Edmonton Valley Zoo but was born elsewhere; I do not know if there are other individuals. Fort Wayne: Home to a mated pair, Lionel & Dieng, and at least two male offspring, Jaka and ? (as of 2013). Lionel is from the GCC and Dieng is from Belfast. Greensboro: Home to a mated pair, Bella & Leon (from where?), and offspring, a male (Duke) and one of unknown sex born last year. Winnipeg: As of 2009 a female (Willow) was still at Winnipeg; I don’t believe she is now, but I don’t know where she moved to. Finally, does anyone know what happened to the animals that lived at Rushden or Paignton in the '90's?
