Profile

Picture: Ryukyu Flying Fox (6 Kb JPEG)

The Ryukyu flying fox utilizes forest for daytime roosting. It eats the fruits of a variety of plant species. Figs are a favorite. It lives in colonies.

The Ryukyu flying fox occurs in the Ryukyu Archipelago (Japan). It previously occurred in Taiwan. It is abundant in the southern and central parts of Okinawa. Populations appear to be large on Ishigaki, Iriomote and Yonayuki. (WCMC/WWF 1997)

Threats apparently include hunting and deforestation on different islands.


Tidbits

*** 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.

*** The Ryukyu flying fox can be a pest of commercial fruit crops.
