That's a shame , hope you one day are able to see some of these in the wild. Personally I would love to see a purple faced langur in either captivity or the wild , I'm yet to see one or indeed a douc langur which also really interest me. The only species you mention that I've seen in the wild is the black lion tamarin. Back in January of this year I worked for about two weeks with a Brazilian conservation NGO closely associated with the Durrell trust with wild black lion tamarins in Morro do diabo National park. It was an experience I'll never forget.
I've seen all the subspecies of Purple-faced Langurs and all three Douc species (although I haven't seen the Grey-shanked in the wild yet).
One can only hope - one of the two subspecies I have seen (nestor) is in severe decline and is now classified as Critically Endangered, the population having reduced by c.80% in the last three generations.
My favourites: Red Howler Black Lion Tamarin Red backed Saki Purple faced langur Red shanked Douc Hamlyns owl monkey Spix's night monkey Golden bellied mangabey Roloway monkey Crowned Guenon Hecks macaque These are species I have seen in at least one place but make the list mainly for rarity More common species I like to see would be: Lion tailed macaque Gelada L'hoests monkey Patas monkey Drill
Indeed, totally agree, lets hope that it is able to somehow survive the anthropocene. I have a very clear memory of seeing a purple langur as the cover photo on an issue of National Geographic magazine years ago which I guess was where I learned they existed from. Ever since I've always thought they were quite a charismatic species. What zoo did you see this species in ? Was it in Europe ?
Very impressive indeed , were they hard to spot or habituated to humans ? I'd love to see one of the Douc species in the wild someday though I know I probably won't get round to it, I just find them fascinating.
Here are my five favourites (all but the Proboscis Monkey I've personally seen). Red Uakari Japanese Macaque Lion-Tailed Macaque Golden Lion Tamarin Proboscis Monkey
vetulus - Edinburgh Zoo, on several occasions between 2010 and 2012. nestor - Cotswold Wildlife Park, on several occasions between 2012 and 2015.
Sadly it appears these are no longer being kept by either of those zoos, is this another species that zoos in Europe are allowing to fade out from their collections ? If so then I dont really know what to say other than it is quite depressing that there isn't more interest in maintaining ex-situ a species which is so clearly on the brink of extinction in the wild.
Its mine also... Other favourites include(roughly in order); Cherry-crowned/Red-capped Mangabey. Drill. Liontailed Macaque. Gelada De Brazza guenon. Diana Guenon. Spectacled Langur. Hanuman Langur. Golden Bellied Mangabey. Mandrill. Douc Langur.(many years since I saw these though)
Personally my favorites are the Papio baboons followed by the Patas monkey and Gelada. I also like Grey-Cheeked & Golden-Bellied Managabeys. The male Golden Bellied in Cleveland made the funniest faces when I filmed him. And of course, Langurs are always fun to watch! I'd like to see more primates such as Hamlyn's (Owl) Monkey as well as others such as the Roloway Monkey, Sumatran Surili and Purple-Faced Langur.
lion tailed macaques, mostly because the babies look so cute with there long and gray beards. Good old Bartaffen
all neotropical species especially wooly monkeys, marmosetts, tamarins. I have seen wild specimens during travels.
Drill, Lesser Spot-Nosed Monkey, Mustached Guenon, Grey Woolly Monkey, Red Uakari, and Stump-Tailed Macaque are some of my favorites of the ones I've seen.
The Mandrill, without a shadow of a doubt, gets the first place for me. Apparently studying a species intensely for months will do that to you.
