Why scientists are using thermal drones to count flying foxes in Australia

As pollinators of the forests, the iconic gray-headed flying fox, a megabat native to Australia, plays an extremely important role in the continent’s biodiversity. But the species is increasingly at risk of extinction. And effective monitoring has become imperative for more reliable conservation management.

Problems with wildlife ground surveys

Typically, wildlife biologists have relied on manual ground surveys to detect and monitor flying foxes.

Multiple human counters are designated to flying fox colonies to monitor the furry creatures: first, during the day when the flying foxes are roosting and static, and second, during the evening when they leave the roost to forage on nectar and fruit and can be spotted individually as they depart.

However, these methods have their limitations. As John Martin, a research scientist at Taronga Conservation Society, points out:

The terrain can be difficult and physically…
