The condor owl was a crepuscular gliding or flying predator that attempted to swoop and catch prey, then drop it on rocks from a great height. It was a hexapedal mammal, with the fore-limbs specialized into wings, and folds of skin that gave additional gliding and lifting surface when the midlimbs were extended, with the back four limbs holding grasping talons. Their large eyes were forward facing. Condor owls had very acute vision and were capable of taking even an adult treecat or even larger game if they could suprise one. They were even considered a threat to humans.
