Gould's Long-eared Bat

Fascinating facts about the Gould's Long-eared Bat

• Gould's long-eared bat is one of the most common microbats in Australia and is described as an ecological generalist. It thrives in a variety of wet and sclerophyll woodlands and forests, exploiting the abundant insect prey found there. Its range even pushes into semi-arid zones that follow river corridors, showing a tolerance for drier conditions. This flexibility allows the species to occupy many different landscapes across its eastern and southern distribution.
• In the cooler months of southern Australia the bat enters a hibernation period that can last from April-May through to September. During this time it relies on stored body fat to maintain a prolonged torpid state, extending each bout of reduced metabolism for up to eleven days. By conserving energy in this way, the species can survive the winter when insect prey become scarce. The hibernation strategy is a key adaptation for enduring the austral winter.
• Gould's long-eared bat forms daytime roosts that may contain as many as twenty-five individuals. These colonies are found under loose bark, inside tree hollows, in abandoned bird nests and occasionally in buildings, providing both shelter from predators and communal warmth. While males often roost alone, the larger groups are typically composed of females and juveniles. Such flexible roosting behaviour supports the species' wide distribution.
• A 2021 taxonomic review split the western Australian population from its eastern relatives, naming the new species Nyctophilus holtorem. The revision was carried out by Parnaby and colleagues, who highlighted the distinctiveness of the isolated south-west range. This separation reflects the bat's distribution, which spans eastern Australia from Queensland to Victoria while a smaller, disjunct population persists in southwestern Western Australia.

About the Gould's Long-eared Bat

In the warm, golden light of dusk, the Gould's Long-eared Bat stirs, unfolding its delicate, almost translucent wings like a dark, leathery cloak, as it prepares to take to the evening skies. With a fluttering, erratic flight, it dances through the trees, its oversized ears twitching with every subtle nuance of sound, guiding it with unerring precision to the faint, high-pitched calls of its insect prey. As it hunts, its very presence seems to embody the whispered secrets of the night, a fleeting, mysterious apparition that vanishes as suddenly as it appears.
