I don't know where you're getting this stuff from but the link I gave you was to the actual Australian Museum.
Drop Bear (australian.museum)
Feeding and diet
Stories of kill sites and examination of scats suggest mainly medium to large species of mammal make a substantial proportion of the animal's diet. Often, prey such as macropods are larger than the Drop Bear itself.
Drop Bears supposedly hunt by ambushing ground dwelling animals from above, waiting up to as much as four hours to make a surprise kill. Once prey is within view, the Drop Bear will drop as much as eight metres to pounce on top of the unsuspecting victim. The initial impact often stuns the prey, allowing it to be bitten on the neck and quickly subdued.
If the prey is small enough Drop Bears will haul it back up the tree to feed without harassment from other predators.
Would an actual Museum lie to you??
