A large area with Ring-tailed, Black-and-White Ruffed, Red-fronted, Mongoose, Red-bellied and Alaotran Gentle Lemurs, as well as various birds (mostly seeming to be spare birds from groups elsewhere in the park, such as Kenyan Crested Guineafowl).
After three passes through, we spotted four of the six lemur species - Red-bellied and Alaotran eluded us! It's a nice broad selection of lemurs though.
