Climate, diet, problems with digestion in captivity( leaf-eaters in particular), rarity in the wild leading to unavailability.
Or lack of interest? Our Sanford's Lemurs had been contraceptive implanted by Duke University because with a captive population of 14 animals, they could not generate any interest. We persuaded them to send the animals to us and Banham, but they never recovered from the implants, became grossly obese and never bred. We bred many Weddell's Tamarins (15!) from a pair received from Banham, but could not place the young, and after losing the whole group of 17 animals to yersiniosis (in hind-sight, possibly exacerbated by over-crowding) we never attempted to replace them.

I think a lot is due to the education and marketing departments of zoos. Many exhibits have little notices listing the common name, Latin name and perhaps a little map. These are unlikely to attract a visitor who goes part an exhibit after seeing an animal there. I remember a zoo exhibiting a paradise tree snake. If the notice had said that the 'flying' snake glides between trees and perhaps shown a video, more visitors may have been interested. Several exhibitions in museums show a range of audio-visual display material to interest visitors. Many zoos should use similar techniques.
Yes- I reckon this is one of things the Natural History Museum does better than both its French counterpart and (almost) all zoos. People actually get interested in the animals because there are interactive displays, where visitors can weigh or measure themselves against a Blue whale or squid. I know quite a few people who would prefer to go to the museum over the zoo (and not only because it's free) because they could spend half an hour on an interactive display and learn new things without having to read a bland noticeboard.
Indeed, their collection is not that good, it depends a bit on what they receive from confiscations and how long they can keep them alive. In January I saw: 2 species of spider monkeys (C + B) 2 subspecies of woolly monkeys (P + T) Capuchins (macrocephalus and yuracus) Saki monkeys (inusta) Titi monkeys (discolor) Squirrel monkeys (peruviensis) Night monkeys (nigriceps?) Ouakaris (ucayali) Saddle-back tamarins (leucogenys) Pygmy marmosets
Thanks! They had a little more last time I was there, including a further saddleback tamarin taxon and blond saki.
According to LTS, Los Cristanos has monkeys in 2 animal collections: The Las Aguilas Jungle Park contains: Common marmoset Black-capped and white-faced capuchins, common squirrel monkey De Brazza’s monkey The Monkey Park contains: Black tufted-ear, common and Geoffroy’s marmosets, callimico, cotton-top and golden-handed tamarins, red-mantled saddle-back tamarin, golden-headed lion tamarin Common squirrel monkey Stump-tailed macaque, black-crested mangabey, drill, Allen’s swamp monkey, patas monkey, northern talapoin, De Brazza’s, Roloway, Syke’s and Lowe’s guenons, grey langur
I'm posting this here because I guess the people concerned are watching this thread. Can you inform me about the missions of an ethologist and more particularly of a primatologist? Are there any on this forum?
Ethologists study the natural behaviour of animals in the wild. Primatologists study primates. They may study the behaviour of primates in the wild or may be concerned with classification or anatomy etc.
Thanks but this is very general. Does he really work in nature or rather in the laboratory? What exactly are these missions? Does he have to work with zoos and why?
Please note that ethologists can be male or female. 1 Ethologists tend to work in the wild in order to view natural behaviour. It can take a long time for some animals to get used to scientists and disregard them, so some observed behaviour may not be natural. Ethologists can work in a laboratory with some smaller animals, as long as the animals' 'habitat' replicates their habitat in the wild. Some primates are kept in laboratories and may be studied by primatologists, but the behaviour of laboratory primates may not represent their behaviour in the wild. 2 Those depend on what the scientists are aiming to achieve. 3 No. Some ethologists and primatologists have nothing to do with zoos. Various zoos have representatives in different parts of the world in order to learn about animals. This helps the zoos to understand how to keep captive animals and can help to conserve various species by liaising with representatives of different nations.
Ok thank you for this information. Yes obviously I only put it to lighten the text but if you have to put he / she I would do it in the future.
This is not necessarily true, there are a lot of ethologists working in captive situation in testing rooms that don't reflect wild habitats. Such circumstances are necessary to understand the mechanisms behind behaviour among other things. If you are interested in ethology any book by Frans de Waal would be interesting, he focuses mostly on primates, but also has some stories to tell about birds and other animals.
