Natural Predators:
* Dingoes: These wild dogs are a significant predator of bilbies, especially in areas where they are abundant.
* Foxes: Introduced red foxes are particularly problematic, as they are highly adaptable and effective predators.
* Wild cats (Feral Cats): These introduced felines also pose a threat to bilbies, particularly kittens and young adults.
* Goannas: These large lizards can prey on bilbies, especially in areas with limited other food sources.
* Birds of Prey: Birds such as wedge-tailed eagles and brown falcons can occasionally take adult bilbies, although they more typically prey on young or injured individuals.
Introduced Predators:
* Red foxes: These are a major threat to bilbies, especially in the arid and semi-arid regions where they are abundant. They have a devastating impact on bilby populations.
* Feral cats: Like foxes, feral cats are highly effective predators and have contributed significantly to the decline of bilbies.
* Rabbits: While not a direct predator, rabbits compete with bilbies for food and resources, further impacting their survival.
Other Threats:
* Habitat Loss: Land clearing for agriculture and urban development has drastically reduced the amount of suitable habitat available for bilbies.
* Climate Change: Drought and extreme weather events can impact bilby populations, leading to reduced food availability and increased vulnerability to predators.
* Disease: Introduced diseases, such as the rabbit calicivirus disease, can have a significant impact on bilbies, even if they are not the primary target.
It's important to note that these are just some of the enemies of bilbies. Understanding the complex interplay of these threats is crucial for developing effective conservation strategies for this vulnerable species.
