Its call sounds like a wail or a scream in the night. When scared, it screeches – a sound similar to the screech of a possum.[8] A field report from Brookton, Western Australia noted that their call was heard in response to the cry of possums shot by hunters.[9] When threatened (presumably in the presence of a nest), they may raise their wings wide and high in an impressive threat posture and emit a loud, hoarse hissing noise.
