The former orang/siamang exhibit has been heavily reconstructed - removing roof and walls to make the central exhibits a pleasant outside area and using the end exhibits for indoor accommodation.
Be carefull Lintworm. I might come to Holland this winter and I WILL find you
I am just saying that what makes Madagascar unique in a biological sense is that such a relatively small island comprises so many different habitat types and that is the reason that you can see such a broad diveristy in the around 100 different types of lemurs on the island.
I just wish more zoos would emphazie this and not just cram the usual ring-tailed lemur/ruffed lemur/brown lemur/black lemur combination into the same exhibit. Three of these species would NEVER meet in the wild and even live in very different habitats.
