The brown mouse lemur (Microcebus rufus) is also called the rufous mouse lemur, the Eastern rufous mouse lemur or the russet mouse lemur. Do predators influence the behaviour of bats. Solitary species like mouse lemurs have to individually learn to associate predator calls with danger which is dependent on encounter rates. This is an alarm and can be howling which can be heard for a long distance. I hypothesized that wild brown mouse lemurs (Microcebus rufus) in Ranomafana National Park, Madagascar, differentiate between predator and non-predator vocalizations and exposed 29 adult subjects to calls of 3 sympatric predators (goshawk, fossa and owl), 3 sympatric non-predators and 4 controls.
