Chocolate Wattled Bat

The Chocolate Wattled Bat (Chalinolobus morio) is a small insectivorous bat in the family Vespertilionidae, endemic to Australia, where it is one of the more widespread members of the genus Chalinolobus — the wattled bats, named for the fleshy lobes (wattles) at the corners of the mouth. Chalinolobus morio is uniformly dark brown to chocolate-brown in colour, compact in build, and has the short, broad wings characteristic of bats that forage in cluttered forest environments at moderate to low altitudes. It is distributed across much of temperate and subtropical eastern Australia, southwestern Australia, and Tasmania, inhabiting diverse forest types from eucalypt woodland and mallee to tropical dry forest. The species roosts in tree hollows, bat boxes, and occasionally in buildings, sometimes forming small colonies. It feeds nocturnally on moths, beetles, mosquitoes, and other flying insects, using echolocation to detect and pursue prey. Like other hollow-dependent bats in Australia, populations are sensitive to the loss of large, old eucalypts with natural cavities. The IUCN classifies Chalinolobus morio as Least Concern given its broad distribution and relatively large population across Australia. Ongoing threats include hollow-bearing tree removal, roost disturbance, cat predation, and barbed wire entanglement.
