At Parc Ivoloina the group learned two field survey methods, sample scanning and focal point. Sample scanning involves a stop watch and a population of animals. Every twenty seconds each posture and locomotion type is recorded. This is repeated for a set amount of time, say ten minutes. Focal Point study involves following a single animal for a set amount of time and recording every locomotion change or position change. One of the short hand notes is OOS or out of sight. One of the lemurs surveyed was the red belly lemur.
Eulemur rubiventer, red belly lemur, is a medium sized lemur weighing 2kg. The fur is a dark chestnut brown and they have black tails. Males have pale tear drop patterns around the eyes. Interesting fact, after infants are 5 weeks old the father will carry the child until the child is a 100 days old.
