The Giant Flying Fox

Jun 3, 2026

At the start of the video, a large bat is seen hanging from a support rope within the enclosure. The camera then performs a motorized pan to the right, sweeping past a green structure and enrichment items like a hanging white snuggle ball, eventually settling on a wide view of the netted habitat's perimeter.

Several flying-foxes are hanging upside down from the mesh ceiling and branches of an outdoor enclosure. One individual in the center-left is observed turning its head and shifting its weight. A pink, pig-shaped enrichment toy hangs motionless in the center of the scene, and the surrounding vegetation is still.

Where Does the Black Flying-fox Live?

The Black Flying-fox is native to the tropical and subtropical regions of Oceania and Southeast Asia. Its core population spans the northern and eastern coastlines of Australia, from Shark Bay in Western Australia across the Top End to New South Wales. Beyond Australia, it is commonly found in the lowland areas of Papua New Guinea and throughout several Indonesian islands, including Sulawesi and Sumba.

Behavior

Black Flying-foxes are highly social mammals that congregate in massive communal roosts known as 'camps.' These camps are often located in mangroves or paperbark swamps and can contain tens of thousands of individuals. They are incredibly vocal animals, using a complex language of squawks and chatters to establish hierarchy and defend their personal space within the crowded roost.

As nocturnal foragers, they depart their camps in spectacular 'fly-outs' at sunset, traveling up to 50 kilometers in a single night to find food. They are exceptionally intelligent and have been observed using sophisticated navigation skills to return to the same productive trees night after night. While they can be noisy neighbors in suburban areas, they are harmless to humans and pets if left alone.

Camera Tips

To capture the best footage of Black Flying-foxes, you need to think vertically. These bats rarely descend to the ground, so your AI-powered camera should be mounted high—ideally 2 to 4 meters up—facing a known food source like a flowering Grevillea or a fruiting fig tree. Angle the camera slightly upward to capture them as they glide into the branches or clamber through the foliage using their hooked thumbs.

Since they are strictly nocturnal, a camera with high-quality 'no-glow' infrared LEDs is a must. Standard white flash can startle them and cause their dark fur to appear as a featureless black blob. Set your camera to capture short video clips (15-20 seconds) rather than just stills; the way these bats wrap their wings around themselves or interact with other bats provides much more interesting content than a static image.

You don't need artificial bait, which can actually be harmful to their diet. Instead, focus your camera on 'natural' lures. During hot summer spells, placing a camera near a swimming pool or a garden pond can yield amazing results, as flying foxes will often fly low over the water to 'belly-dip,' licking the water off their fur to stay hydrated and cool.

Finally, ensure your camera's PIR (Passive Infrared) sensitivity is set to 'High.' Because bats move quickly and have fur that insulates their body heat, they can sometimes be missed by less sensitive sensors. A high-speed trigger will ensure you catch the moment they first swoop into the frame rather than just a departing wing-tip.

Frequently Asked Questions

Black Flying-foxes are strictly nocturnal. They are most active from dusk, when they leave their roosts in a mass fly-out, until dawn. You are most likely to see them in your backyard between 7 PM and 4 AM as they forage for nectar and fruit.

The best way to attract them is by planting native Australian trees. They are particularly fond of flowering Eucalyptus, Corymbia, and Melaleuca species. Avoid using bird netting on your trees, as bats can become easily entangled and injured.

Their primary diet consists of nectar and pollen from native blossoms, particularly Eucalypts. They also enjoy native fruits like figs and occasionally visit suburban gardens for mangoes, mulberries, or stone fruit when native food sources are scarce.

Yes, they are very common in suburban areas along the northern and eastern coasts of Australia. As their natural habitat shrinks, they have adapted well to urban environments where garden trees and street plantings provide a reliable year-round food source.

The Black Flying-fox is almost entirely jet-black. In contrast, the Grey-headed Flying-fox has a distinct light grey head and a very noticeable collar of orange or ginger-colored fur around its neck.
