* Birds of prey: Large eagles and hawks, like the Papuan Eagle, pose a threat to young tree kangaroos and sometimes even adults.
* Small mammals: While not a primary predator, some small mammals, like feral cats and dogs, can prey on tree kangaroos, especially young ones.
* Humans: Habitat loss and hunting are significant threats to tree kangaroo populations.
It's worth noting that tree kangaroos have adapted to their environment, developing strong claws and leaping abilities to help them evade predators. They also have a camouflage-like coloration that blends them into their surroundings, making them harder to spot.
