silent and walk softly. The animals will descend from the trees to within , staring back at the humans with equal curiosity allowing themselves to be photographed as they cling to vertical trunks of saplings, and occasionally engaging in a terrestrial scamper. E. rubriventer occurs in five national parks and seven special reserves in eastern Madagascar, but is classified as vulnerable (IUCN Red List) due to ongoing habitat reduction from slash-and-burn farming, illegal logging, and even hunting. The species is the subject of current study in its natural habitat as well as in captivity in research centers such as the Duke Lemur Center.
