I have an earlier post on my blog about real life furbys, actually Pygmy Tarsiers, and I thought I would post a bit more information about them with links.
Pygmy Tarsiers were considered to be extinct, but were recently rediscovered in 2008. They are nocturnal primates which are native to Indonesia, living in the rain forest. A story explaining a bit more about them is posted on Reuters called Tiny, Long Lost Primate Rediscovered in Indonesia.
The University of Michigan Meuseum of Zoology has an entry about these guys explaining their habitat, physical features, and more at Tarsius Pumilius: Pygmy Tarsier.
Here are more pictures:
