The black-eared flying fox (Pteropus melanotus), also known as Blyth's flying fox and Christmas Island flying fox, is a species of bat in the family Pteropodidae. It is found on Christmas Island (Australia), Andaman Islands (India), Nicobar Islands (India), and Sumatra (Indonesia).
Distribution and habitat
The black-eared flying fox is native to various island groups in the Indo-Pacific. These include the Andaman Islands, the Nicobar Islands, the Mentawi Islands and Christmas Island. It mostly roosts in large colonies in forests near the coast, especially in mangrove areas.
The black-eared flying fox is more diurnal than most bats, emerging from its roosts before dusk and feeding on the fruits and flowers of at least twenty-six species of forest trees at least ten of which are introduced species. A single young is born annually.
The black-eared flying fox faces a number of threats. Destruction of its forest habitat reduces the availability of roosting sites and the animal is hunted by man for food. The crushed bones of this species are used in traditional medicine to relieve asthma symptoms. However, it has proved adaptable to changes in diet and now feeds on a number of introduced species of plant. The IUCN has rated this species as "Vulnerable".
C. R. Tidemann reported observing endangering behaviors on a visit to Christmas Island in 1984: "Three behavioural features make P. melanotus easy prey for hunters on Christmas Island even though firearms are prohibited: (1) a pronounced diurnal shift from the usually nocturnal habits of congenerics; (2) a tendency to feed close to the ground, particularly in the exotic shrub of Muntingia calabura; (3) a failure to respond in an appropriate manner to the approach of potential predators. (On Christmas Island P. melanotus has no predators other than man.)"
