With labelling itself as the world primate centre they have never been strong on lemurs.

 

Success with the Langurs seems to be overall intermediate between the Gibbons and the Guenons. I imagine that these results reflect the general difficulty or otherwise of breeding all these various species in captivity as a whole (and not just here) as despite the old fashioned housing at Twycross, it always looks to me as if the animals are very well cared for (as against MANAGED) and they must have a great deal of experience by now with all those species which they keep/kept. That's not to say these results are exactly what you'd expect from a 'global centre of excellence'.

I'm amazed they've only ever bred a single Ringtailed Lemur...

 

I suspect ring-tailed lemurs are amongst a number of species they do not try to breed .

I agree the animals do look well cared for . I really do not like the tiny inside areas in most houses - I wonder if all stock is shut in outside of opening hours , I hope not . Even if not shut in , during winter they must be stuck inside for very long periods every day .

There are no representatives of Macaques or Baboons in the collection either - I seem to remember being told once that Molly did not like them .

 

The animals as far as I know have access to indoor and outdoor all year round. I have seen a few cases where an aniamls maybe shut indoors or out doors and these have been with the Bonobo's (one group has to be shut in all day while the other group gets access to outdoor enclosure aswell the indoor) and the orangutans (I think they had two groups at one stage and there one group had to stay indoors in very crampted conditions)

I have a question someone may be able to answer, does the Bonobo house have off show den's? I have never noticed before and can't remember seeing any?

 

There are a number of small dens running down both sides of the Bonobo House . There are windows ( not proper viewing though ) and I have seen one bonobo being held apart from the group on a past visit .

 

The Apes don't have free access, at least they didn't used to. UNLESS there have been changes, they are shut indoors at night into the small individual sleeping dens where they are fed in them just as the zoo closes. I'm pretty sure they stay in them overnight, though not absolutely sure on that. If so, that's from about 5p.m through to the next morning.
In the orangutan and chimp houses there are glass viewing windows into the dens. The orangs certainly used to look as if they've been put in theirs for the night... In the gorilla and Bonobo houses these dens(actually wire mesh boxes) are offshow though there are small blacked windows along the outside walls..
The Bonobo House and older Gorilla House have the same arrangement- about three dens offshow on each side of the house. In the newer Gorilla house the dens are on one side only, the one nearest the old Gorilla enclosure.

I wonder how many other species there are actually allowed free access? Twycross is not a very secure site and a fairly easy target for vandals or other nightime visitors.

 

Yes, I'm sure they don't try to breed ringtails, but I'm still surprised they've only had a single birth. If you have a pair or group, you can normally expect results. (not Twycross bashing, but its a fact)

I was told they did have Lion -tailed Macaques for a very short while (circa 1980's?) but that they ripped up the manicured turf in the enclosure so were hastily moved out. Not sure if thats true though...

 

Yes - a pair of lion-tailed macaques arrived at Twycross on 29.10.1975 , the female from Widdington ( ? Mole Hall ) , male unknown origin . They were moved on to Bristol on 14.7.1976 . The male died at Bristol in 1979 , the female ended up at Regent's Park in 1983 where she died in 1985 .
Details from 1991 Studbook .

 

So Twycross had them about nine months. I can believe them tearing up the grass as they are very hard on enclosure vegetation(Colchester's is bare earth, Bristol's was heading that way to start with). I saw the pair at London Zoo, they came from Bristol who at that time had two pairs- of which this was the older non-breeding pair.

 

Twycross are planning to rotate the lions and dholes between enclosures in their planned new exhibit. The planning application has not yet been submitted.

 

WOW, another wonderful idea for from Twycross Zoo.

Why doesn't this surprise me!

 

I think Chris means that two exhibits will be built and the lions and dholes rotate between them, like zoos in the US do (rather than one species stays indoors and the other is outside)

 

Lets hope so.

 

Oops, yes Jimmy is right, I didn't realise it was so ambiguous. Here is the exact wording from the Trustees' Report:

 

Still the money spent on this could be better spent on their existings enclosures.

 

It's good too see Dholes getting a prominent exhibit in a UK zoo and it's even better to see Twycross showing a little bit of creativity in the proposed design of the new enclosures (there aren't any rotation exhibits in the UK are there?)

However I would still prefer the money to be spent on a great ape exhibit (or exhibits!)

 

Who knows what they have design? Maybe another brick house similar to what they create for their gorillas?

Has anyone seen any plans?

Just the Apes left now , should be easier than this last section .

Re Bristol lion-tailed macaques metioned by Pertinax , the breeding group including the 1-handed female were previously at Thorney - I saw them there not long before it closed .

 

a brick house is a given only joking, but what I meant by "design" was they've shown some initiative by proposing a rotation exhibit
