I've been trying to get a handle on all the Francois Langur operations at Taronga. There's a few pieces missing.
Francois Langurs at Taronga:
2004: one pair imported from Nagoya Zoo (Japan): male Hanoi and female Saigon. So 1.1 total at the zoo.
March 2009: female Elke born (first offspring at the zoo), making 1.2 total.
April 2010: male Gan Ju born, died about 3 weeks later. So still 1.2 total.
2010: a second pair imported from Beijing Zoo (China): male Bobo and female Meili. (Meili was placed with the original pair; Bobo was paired with Elke). So now 2.3 total.
Jan 2011: male Keo-co born (to Hanoi and Saigon), making 3.3 total.
August 2011: male Tam Dao born (to Hanoi and Meili), making 4.3 total.
*The census for the end of 2012 says 4.4, which means a female must have been born or imported during 2012 but I haven't been able to find anything on that.
June 2013: female Nuoc born, died one month later. So still 4.4 total.
*The census for the end of 2013 says 3.4, which means that a male has died or left the zoo (perhaps Hanoi left in 2013?).
*The comment on Flickr (see the previous post) says that in May this year (2014) the original female Saigon had left the zoo (which would take them down to 3.3) but two new females had arrived (from where?), which would take them up to 3.5?
