The Orii flying fox is a subspecies of the Ryukyu flying fox.
This flying fox lives nowhere but the Okinawa Islands, and it is active during the day as well as at night.
It chews fruit to a pulp and swallows just the juice, spitting out the seeds and fibers in a lump.
In the winter breeding season, males rub their bodies against trees and other objects to leave their scent.
How the Orii's flying fox lives
They use forests as daytime resting places. They eat plant leaves as well as fruit. They live in colonies and usually use the same resting sites.
