The giant golden-crowned flying fox (Acerodon jubatus), also known as the golden-capped fruit bat, is a species of megabat endemic to the Philippines.

The extinct subspecies (A. jubatus lucifer) was formerly recognized as a full species, the Panay golden-crowned flying fox.

Predators of the giant golden-crowned flying fox include raptors such as eagles, the reticulated python, and humans.

An early description of this species may be found in William Dampier's account of his circumnavigation, A New Voyage Round the World.

[3] The giant golden-crowned flying fox was described as a new species in 1831 by German naturalist Johann Friedrich von Eschscholtz.

[5] The holotype had been collected on the Philippine island of Luzon during an expedition led by Otto von Kotzebue.

[9] A. jubatus lucifer, commonly the Panay golden-crowned flying fox, is still sometimes considered an extinct species of megabat.

The great flying fox has a slightly shorter forearm length, and its wingspan is thus presumed to be lesser as well.

It has golden coloration that begins between its eyes and terminates to a narrow "V" shape at the nape of its neck, though sometimes extending to the upper shoulders.

[11] The giant golden-crowned flying fox is largely frugivorous, though it also consumes plant leaves (folivorous).

[17] The results support that the primary food group is composed of fig species, including Ficus subcordata and unidentified leaves.

[20] It forms harmonious mixed species colonies with another megabat, the large flying fox (Pteropus vampyrus).

[22] Based on limited observation, it is thought that females may not reach sexual maturity until two years of age.

[23] Although they typically live a long life in the wild, they are also hunted by humans and other apex predators such as the Philippine eagle.

[1] Like many bat species, the giant golden-crowned flying fox has been investigated as a source of emerging infectious disease.

One study tested for the presence Reston virus, a kind of Ebolavirus that affects some primates (though not humans), in a population of giant golden-crowned flying foxes at Subic Bay.

[17] Surveys reported in 2005 and 2011 documented this species on the islands of Bohol, Boracay, Cebu, Leyte, Luzon, Mindanao, Mindoro, Negros and Polillo.

[19] The giant golden-crowned flying fox is threatened by deforestation and has completely disappeared from many islands in the Philippines, such as Panay and most of Cebu.

In 1990,[1] two of the three subspecies (A. j. lucifer and A. j. mindanensis) were included on CITES Appendix II, meaning that trade of the taxa was strictly regulated.

Even though hunting pressures are lessened at these three roosts, the giant golden-crowned flying fox contends with other sources of disturbance.

[33] Actions that BCI has taken to promote its conservation include partnering with local non-governmental organizations (NGOs) to protect its roosts, as well as educate Filipinos about bats.

[34] Some captive breeding programs exist for the species, though it is uncertain if they are sufficient to make up for population declines seen in the wild.
