Dusky flying fox Dusky flying fox The dusky flying fox ("Pteropus brunneus"), also known as the Percy Island flying fox, is an extinct species of flying fox in the family Pteropodidae. It was endemic to Percy Island off the southeast coast of Mackay, Queensland, in the northeast corner of Australia. Only one specimen is known to exist. It was documented in 1859 and collected by Dobson in 1878. Since that record, no further documentation is known of this species. Currently, the specimen is located at the British Museum of Natural History, and was validated as a separate species in the late 20th century.
Rennell flying fox 1962, Hill published that he considered Rennell's flying fox as a subspecies of the Solomons flying fox, with a trinomen of "Pteropus rayneri rennelli". The forearm of the holotype was long. The fur of its back is uniformly brownish, with the fur of its neck and face lighter. Females give birth to one offspring per litter, with the young called a "pup." Its lifespan is estimated at 8–9 years. It is nocturnal, roosting in sheltered places such as trees during the day. Individuals roost by themselves. It is only known from Rennell Island, which is part of the Solomon Islands.
