How can you observe the Large Flying-fox?

Watch from a distance, do not feed, and avoid sharing precise locations of vulnerable dens or resting sites. Do not try to catch or touch wild mammals. A well-documented sighting helps others check the identification without turning one encounter into a conservation-status claim.
