The Field Guide to the Birds of Australia tells us the other names for the Blue-Winged Kookaburra are Barking Jackass and Howling Jackass. The authors appear unable to hide their uneasy feelings about this bird. When describing the sound of its call, they write this: Appalling; a gutteral ‘klock, klock’, developing into a cacophony of mechanical squawks and screeches.
Imagine the authors crouched beneath a tree filled with appalling Howling Jackasses screeching mechanically, and there they are, the authors with their hands over their ears, and tears streaming down their faces, shrieking in horror, “Stop! Make it stop!!”
