The eastern free-tailed bat is a species of bat found in Australia
Taxonomy and etymology
It was initially described as a subspecies of Loria's mastiff bat, Mormopterus loriae. In 2008, it was elevated for the first time to species rank—a view that was further corroborated in 2014 when a genetic analysis of Australian Mormopterus was published.[2] The eponym for the species name "ridei" is likely William Ride, who was an accomplished Australian zoologist.
Description
It is a smaller member of its genus, with a body mass of 5–11.2 g (0.18–0.40 oz). Its forearm is 30–35 mm (1.2–1.4 in) long. Fur color is highly variable among individuals, with some bats a light brownish-gray while others are darker brown.[2]
Biology and ecology
It is nocturnal, roosting in sheltered places during the day such as inside Eucalyptus tree hollows or in buildings.[2] It is insectivorous, often foraging near habitat edges.[3]
Range and habitat
It occurs along much of the eastern coast of Australia . It is generally found in areas with more than 500 mm (20 in) of annual rainfall.[1]
Conservation
It is listed as least concern by the IUCN—its lowest conservation priority. It meets the criteria for this category because it has a very large extent of occurrence, a large estimated area of occupancy, it uses a wide variety of habitats, and its range includes protected land. However, the IUCN assessment does express uncertainty over its population trend; it is unknown if its population is stable or declining.[1]
