Habitat
Greater bilbies inhabit arid and semi-arid regions of Australia, including deserts, grasslands, and shrublands with sandy soils that allow for burrowing. They prefer areas with spinifex grasses and acacias for cover and food sources. These habitats are typically hot and dry, with bilbies adapting by digging extensive burrows.
Diet
Greater bilbies are omnivorous, feeding on insects like beetles and termites, as well as plant matter such as seeds, bulbs, and fruits. They forage nocturnally, using their keen sense of smell to locate food buried underground. Their feeding behavior includes digging small pits to access roots and invertebrates.
Behavior
Greater bilbies are primarily nocturnal and solitary, emerging at night to forage and dig burrows that can be up to 3 meters long. They exhibit territorial behavior, marking their areas with scent glands, and are generally elusive, relying on their excellent hearing and burrowing to avoid threats. Males may travel farther than females in search of food or mates, but they do not form social groups.
Conservation Status
The greater bilby is classified as Vulnerable by the IUCN, with populations declining due to habitat destruction, introduced predators, and competition from livestock. Major threats include ongoing land clearing and predation by foxes and cats.
