Two large bats are hanging upside down from the mesh ceiling of an enclosure. The bat on the left is active, shifting its head and displaying its prominent reddish-brown mantle against its dark body. The enclosure includes climbing ropes and a mesh wall with sunlight filtering through from the background.

Several flying foxes are resting in an enclosure, hanging upside down from a metal support bar. A light rain is falling, visible as streaks across the frame. One bat in the center is particularly active, shifting its position and grooming its wings, while a very large, out-of-focus individual is perched directly in front of the camera lens on the left.

Several large flying foxes are seen hanging upside down from a mesh ceiling within an enclosure. A prominent bat in the foreground shifts its weight and turns its head, while another individual in the background can be seen eating a piece of fruit. The bats use their hooked feet to maintain their grip on the mesh as they rest and feed.

Several large bats are seen roosting in a sunny enclosure. One individual hangs prominently in the foreground, wrapped in its wings, while at least three others are visible hanging from the mesh ceiling further back in the shade. The bats remain mostly still during this daytime observation.

A flying-fox is roosting at the top of the enclosure, partially tucked behind a large, pig-shaped plush toy hanging from the ceiling. The bat remains mostly stationary in its upside-down position, though it can be seen moving its head slightly near the attachment point of the toy.

A Black Flying-fox is seen hanging upside down from a mesh ceiling, actively grooming its fur and wings. It uses its mouth and the claws on its wing thumbs to meticulously clean its membranes and torso.
Geographic range
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.
