Play the sound Whippoorwill whistle:
This MP3 audio sound quote is from:
Legendary writers H.P. Lovecraft and Stephen King often used the appearance of Whippoorwills as a symbolic harbinger of death to come in there horror novels. But that doesnt mean you can't enjoy the Whippoorwill song and bird calls. Its call is vigorous yet truely unique and pretty if heard from afar.
