If you didn't know what sound the males make when they are looking for mates and you heard one on a dark night walking through the bush you would swear you are about to be attacked by a lion.
We had one in residence for a month and a half in a tree outside my daughters bedroom window one time. The noise every night was that bad I sharpened the chainsaw ready to cut his house down. Pickings must have been slim in that area because he up and left before I got around to it.
