* Foxes: Introduced foxes are opportunistic predators and can sometimes hunt kangaroos.
* Wild Dogs: Wild dogs, like the dingo, can pose a threat to kangaroos.
Competitors:
* Other Kangaroos: Competition for food and resources exists between different kangaroo species, and even within the same species.
* Sheep and Cattle: Introduced livestock can compete with kangaroos for grazing land, leading to conflict.
* Rabbits: Rabbits, another introduced species, can outcompete kangaroos for food and resources.
Symbiotic relationships:
* Birds: Some birds, like the Red-capped Robin, benefit from the foraging activities of kangaroos, finding insects disturbed by them.
* Insects: Kangaroos can attract insects, providing food for other animals.
* Plants: Kangaroos play a role in seed dispersal by eating fruit and dropping seeds in new locations.
Other Interactions:
* Humans: Kangaroos often encounter humans, especially in agricultural areas, leading to potential conflicts.
* Domestic animals: Kangaroos can interact with domestic animals, such as dogs and cats, leading to unpredictable outcomes.
It's important to note that the specific animals kangaroos interact with vary depending on the location and specific species of kangaroo.
