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.
Animal echolocation available for reflecting off objects and being heard by the bat. The time interval between subsequent echolocation calls (or pulses) determines two aspects of a bat's perception. First, it establishes how quickly the bat's auditory scene information is updated. For example, bats increase the repetition rate of their calls (that is, decrease the pulse interval) as they home in on a target. This allows the bat to get new information regarding the target's location at a faster rate when it needs it most. Secondly, the pulse interval determines the maximum range that bats can detect objects. This is because bats
