Madagascan rousette of the genus "Rousettus", these bats reside within cave roosts, suggesting the use of echolocation. These bats are a part of a larger group of fruit bats within "Rousettus" which consists of 10 different species. The Madagascan rousette primarily resides on western Indian Ocean islands. The habitat of the Madagascan rousette is generally found to be associated with forests. They will roost well beyond the time of twilight. Many roosts have been found within caves however some bats have been found without a known cave roost, suggesting that the Madagascan rousette may sometimes roost within tree holes or other alternatives.
Human echolocation details about their environment; however, others actively produce mouth clicks and are able to gauge information about their environment using the echoes from those clicks. Both passive and active echolocation help blind individuals learn about their environments. Because sighted individuals learn about their environments using vision, they often do not readily perceive echoes from nearby objects. This is due to an echo suppression phenomenon brought on by the precedence effect. However, with training, sighted individuals with normal hearing can learn to avoid obstacles using only sound, showing that echolocation is a general human ability. Vision and hearing are closely related
