Very little information has been published about the Mortlock Islands flying fox.


*** Flying foxes are so-called because of their fox-like faces. They cannot use echolocation. Instead, they navigate using vision and normal hearing.

*** Most flying foxes eat fruit and are also called fruit bats. Fruit bats are ecologically and economically important because they pollinate and disperse the seeds of wild and commercial plants.

  • WORLD (Mortlock Islands in Chuuk (Truk), Federated States of Micronesia)
    • 1992: Because of the small area of the Mortlock Islands, the population probably does not contain more than several thousand individuals (Mickleburgh 1992)

History of Distribution:

The Mortlock Islands flying fox occurs on the Mortlock Islands in Chuuk (Truk) in the Federated States of Micronesia.

Threats and Reasons for Decline:

Commercial hunting and typhoons are the major threats.

Data on Biology and Ecology


The Mortlock Islands flying fox is one of the species that live in the Polynesia and Micronesia Biodiversity Hotspot (Cons. Intl. 2005).  

Gestation Period:

The gestation period of flying foxes is 4 - 5 months (Bonaccorso 1998). 

Early Development:

The young of flying foxes become independent at 3 - 6 months (Bonaccorso 1998).
