* Dingoes: These wild dogs are the most significant predator of koalas, especially in areas where they overlap.
* Large birds of prey: Powerful birds like eagles and hawks can sometimes prey on koalas, particularly juveniles and those on the ground.
* Wild cats: Introduced feral cats and foxes can also pose a threat to koalas, especially if they are habituated to humans and less wary of their surroundings.
It's important to note that these predators are not always successful in catching koalas. Koalas have developed a few defenses:
* They climb high: Koalas spend most of their time in trees, making them difficult to reach for predators.
* They have strong claws: Their powerful claws help them climb and cling to branches.
* They are nocturnal: Koalas are mostly active at night, which helps them avoid some predators.
However, due to habitat loss, bushfires, and disease, the biggest threats to koalas today are not predators, but human-related factors.
