Egyptian fruit bat their days roosting in trees or caves, often with large groups of other bats, sometimes numbering in the thousands. They emerge from the roost to forage for food in the late evening, and return just before dawn. They hang upside down, with their wings folded closely around their bodies. Egyptian fruit bats, along with other species in the genus "Rousettus", are the only megachiropterid bats to use echolocation, which they accomplish by emitting a series of sharp clicks with their tongues. The clicks are normally slow and constant, but these clicks speed up dramatically when the bats approach an object.
Waterhouse's leaf-nosed bat happen in that last trimester. Like many bats, this species uses echolocation as a means to locate their prey. In particular, "Macrotus waterhousii" uses a low intensity, broadband-like call to aide in their search for food. The maximum frequency of a call is 73.65 kHz with a minimum of 46.19 kHz, creating a bandwidth of 27.46 kHz. The call ranges from about 1 second to 3 seconds. In addition, to echolocation, "M. waterhousii" uses the sound made by the prey itself to locate it. This type of foraging behavior leads to a preference for a cluttered habitat. As "M. waterhousii"
