Looking for bats after dark can help science—and change how we see them

Have you ever heard a high-pitched chirping sound at night? That could be the call of a microbat, a small, nocturnal mammal that uses ultrasonic sounds to navigate and hunt. These bats are difficult to study due to their elusive nature, small size and fast flight. In a recent study, researchers explored whether citizen science could help in finding and studying these bats, while also understanding the benefits for the participants.

The team entrusted bat detectors to volunteers in Western Australia. These detectors convert the ultrasonic calls of microbats into sound recordings that humans can hear, helping identify the presence of different species. Australia is home to over 80 species of microbats, with the City of Wanneroo in Perth serving as the study area.

Volunteers were trained to use bat detectors connected to smartphones and taught about local bat species. After conducting surveys across 23 routes in local bushland, the volunteers recorded five bat species, including the first sighting of the Holt's long-eared bat in the area.

The study also focused on the participants' experiences. After receiving training, they reported increased knowledge about bats, greater connection to nature, and a more positive view of these creatures. One participant mentioned they previously feared bats due to a lack of exposure and the opportunity to safely observe these animals at night provided a new appreciation for them.

These findings highlight the potential of citizen science in filling knowledge gaps about Australia's bats and the enjoyment that can come from discovering these fascinating creatures.
