been documented with the tick Alectorobius camicasi. Internal parasites (endoparasites) are the hemosporidian Plasmodium roussetti, which causes malaria, and the roundworm Nycteridocoptes rousetti. Vocalization Egyptian fruit bats, along with other species in the genus Rousettus, are some of the only megabats to use echolocation, though it is considered a primitive form compared to non-megabat species. A few other megabat species echolocate via creating clicks with their wings. It echolocates by emitting a series of sharp clicks with its tongues and by altering teeth and lip positions. The clicks are normally slow and constant, but speed up dramatically when the bat approaches an object. This allows it to effectively navigate in darkness. It also makes use of a range of vocalizations for communication, including grunts and screeches, to communicate with other bats within the colony. As a result, a large roosting colony can be a deafening cacophony. Additionally, according to several studies, it is thought that because of their constant exposure to thousands of other individuals, they can form their own language to interact with one another about specific topics such as food. Colonies of Egyptian fruit bats develop their own dialects, producing sounds at different frequencies. Egyptian fruit bat pups acquire the dialect of their colonies by listening to their mothers' vocalizations. Range and habitat The Egyptian fruit bat is vastly dispersed across various locations and can be found throughout Africa, the Middle East, Pakistan, and the northern regions of the Indian subcontinent. Other populations can additionally be found in the Mediterranean on the mainland coasts of Cyprus and Turkey. It is the only frugivorous bat species in Europe. Outside of its natural distribution, an Egyptian fruit bat was observed in the Greek island of Kastellorizo during a zoological expedition in 2017. Usually found in various kinds of habitats such as tropical rain forests, savannas, or other forests, the Egyptian fruit bat tends to live in large colonies that consist of thousands of individuals in their established roosts. It prefers to establish roosts wherever there are plenty of fruiting trees nearby; most roosts are in caves. When no caves are nearby, it establishes roosts in cave-like human structures, such as abandoned depots and hangars. Relationship with humans As pests Since fruit bats also eat commercially grown fruits intended for human consumption, many of them are poisoned or otherwise persecuted and eliminated by farmers to prevent crop loss.
