That still leaves the mystery of where the Howletts group went. Howletts have a history with woollys...they had them in the early years through to the start of the 1980's but they died out or were moved away.
This later group arrived in the late 1990's, and were put into the right-hand side of a new monkey cage in Howlett's woods, adjacent to the Dusky langurs, which I think arrived the same time. Part of me thinks the Howlett's animals also originated from apenheul, but my memory is hazy on that one. Last time I saw them there was at least one infant, though it was possibly old enough to have arrived with the group. I cannot work out why they were gone within maybe 5 or 6 years. My only guess is that it was a similar story to the doucs...a couple of important breeding animals died leaving a related group with little prospect of long-term survival and so the group was disbanded. It may well have a lot to do with the fact that the twycross animals are hybrids and the Looe Monkey Sanctuary group certainly aren't up for transfer to any zoos.
