Spectacled Flying-fox (Pteropus conspicillatus) lives in tropical rainforest across Eastern Australia and Papua. Its conservation status is Endangered.

A real field recording of the Spectacled Flying-fox, made in the wild.
A spectacled flying fox can span the length of a school ruler, with its head-and-body measuring 22-25 cm and forearm 16-18 cm, while the biggest individuals tip the scales at up to a kilogram, the same weight as a small laptop. In metric terms the forearm stretches 157-181 mm and the combined head-body length reaches 220-240 mm, showing a notable size range across the species.
Each year a single pup is born after a seven-month (180-day) gestation that starts between March and May, with conception also noted from April to May. Females can breed at just one year old, but males wait three to four years, creating a female-biased colony where the sex ratio can reach 2 females: 1 male. The newborn stays with its mother for over five months, is weaned after four months, and then gathers in distant nursery trees before rejoining the main roost at night. This tightly timed reproductive schedule ensures a steady flow of new foragers to sustain the colony's seed-dispersal role.
A 2018-19 heatwave wiped out more than 20,000 spectacled flying foxes, roughly one-third of the entire species, prompting the Australian government to upgrade its status from vulnerable to endangered in February 2019. The IUCN followed suit in 2020, listing the bat as endangered.
Spectacled flying foxes are rainforest gardeners: about 90 % of their diet is fruit, and the light-coloured fruits they favor are specially evolved to stand out against the dark canopy, ensuring the bats can spot them. By eating and later excreting the seeds, they disperse a wide array of trees, from citrus and mango to the blue quandong, which also feeds cassowaries and melomys. This seed-spreading makes them important for maintaining plant diversity and forest structure across their range.
To reconnect fragmented habitats, a wildlife corridor is being built between the Daintree Rainforest and the Great Barrier Reef on a 213-hectare (526-acre) former banana farm. The project aims to plant 360,000 trees; three years on, 25,000 trees from 180 species are growing, with over 10,765 already in the ground. Funded by $2.5 million raised by Climate Force, the corridor will provide fresh fruit for flying foxes and other fauna, restoring the seed-dispersal highways they need to keep the ancient rainforest thriving.

In the twilight skies of eastern Australia, a majestic silhouette unfolds, as the Spectacled Flying-fox takes to the air, its vast wings beating in a slow, hypnotic rhythm. With eyes shining like dark jewels behind a mask of fur, this creature navigates the world with an almost ethereal ease, its leathery wings propelling it through the darkness in search of nectar and fruit. As it moves, the flying-fox embodies a paradox of fragility and resilience, its very existence a reminder of the delicate balance that sustains life in this precious, dwindling world.
