Australasian Population List Index

Would this mean that Sydney Zoo is where the group of spider monkeys, referenced in the recent article about Orana, were rehomed to?
Yeah those are the males that were held off display at Orana. Fingers crossed they're all still alive and kicking. It's difficult to pin point a facility that may have received them within the region. I've contacted all but a few and none have mentioned having that amount of males, and the males names haven't re-appeared at other facilities (if they were separated and sent off to individual facilities). The only other realistic option is they were sent overseas, which we can't rule out despite the unlikelihood.

I agree it’s unlikely the Orana males were sent overseas. The region doesn’t manage them at the subspecies level and there’s a number of hybrids.

It appears Orana exported those males ahead of attempts to rejuvenate their breeding programme with the arrival of a new male (Tostada) from Hamilton Zoo in 2019. Orana has held spider monkeys since 1981 and but hasn’t welcomed an infant since 2005.

As a side note, behavioural non-breeders and females rejecting offspring seem to be a common phenomenon in spider monkeys - both examples of why continuously breeding (or at least regularly breeding) troops are seen as preferable these days.

At Orana the 5 males were held off display for years due to self/pair mutilation. It is possible these behaviours continued at Sydney Zoo and they were euthanised.?

The Orana display troop did have a male, Jackie Chan, but he was euthanised for being too aggressive to the females. This was prior to Tostada arriving.

That’s interesting. Jackie Chan was born at Hamilton Zoo in 2003 and had a good social grounding. Numerous infants were born in the years either side of him and the breeding male was a socially competent male named Diego, who got on well with the females.

Jackie Chan was transferred to Wellington Zoo in 2009, where it was reported he had successfully mated with a then 16 year old female named Biddy (recently arrived from Auckland Zoo), who was subsequently due September 2009. It was believed other females were pregnant, which is interesting as the birth last year was reported as the first at Wellington since 1994.

It's a possibility. It's either they've all passed or been exported overseas (the latter of which I find unlikely). If they did pass, it's intriguing they all passed away around the same time. Spider Monkeys are fairly long lived animals so it's unusual for that to occur.
 
I am looking at doing some population lists, has anybody done these, are they ok for me to do?

Spider Monkey
Emperor Tamarin
Cotton Top Tamarin
Squirrel Monkey
Possibly a Tamarin Population index

Let me know, thanks

None of these species have current population lists; though before creating a population list for spider monkeys, you should ask permission from @Jambo, who began this research thread and may have intentions to turn it into a population list:

Australasian Spider Monkey Research Thread

I think the general consensus amongst the exisiting population list authors is that species like tamarins and squirrel monkeys would be exceedingly difficult to compile and maintain lists given zoos rarely announce deaths and transfers; and even some births receive no follow up mention (a tamarin has twins, but no mention later of whether they were male or female or what they were called).

By all means, feel free to give tamarins and squirrel monkeys a go; but be warned, it will be a challenge.
 
Ok, I am up for a challenge. I will get to work

@Jambo let me know if a spider monkey thread is that something you would be happy me doing.
Mine would only be of live specimens,
, thanks
@austrlain zoo gower If you are going to do a list for the "Red Handed Tamarin" it was the Darling Downs Zoo that imported them (3 pairs I believe) in very resent times.

That was seven years ago.

Red-handed tamarins are now held at Crocodylus Park, Darling Downs Zoo, Hunter Valley Wildlife Park and Tasmania Zoo.

From the Australian mammals thread re. Red-handed tamarins:

Three pairs were imported by Darling Downs Zoo at the start of 2018. Two pairs remained there and one pair went to Hunter Valley Zoo. They have since bred at both zoos. Tasmania Zoo obtained a pair in December 2022, and Crocodylus Park in late 2023.

I found it difficult to compile an accurate list due to some facilities being unwilling to answer queries.

You can go through my research thread, do some research of your own and create a thread if you manage to get the info from every facility.

Feel free to PM me if you have any other questions too
 
@Jambo , thanks you so much. I was thinking of just doing current populations so would hopefully be a little easier. I will have a read through the thread
Yeah I was only looking at the current populations too. Most facilities were helpful with questions of mine, but others not so much!

Considering Spider Monkeys are also a species that have limited mentions on socials it can be difficult to get an even somewhat accurate perception of their population. I wish you luck!
 
Out of curiosity would an Australian captive marine mammal population thread be viable to make on here? That would be super interesting!
