Not sure if this link is going to work, but this morning I recorded the sound of a whippoorwill. You’ll have to turn up the volume to hear it because I just used my phone recorder to do this.
It’s not a sound a person can hear just anywhere any more. Habitat for the bird must be important because I only hear them in places that still have dirt roads. Sometimes there are so many of them here the sound can become irritating – especially when they are cranking up in the wee morning hours on a Saturday morning.
