As I was in bed last night I heard the coyotes. It scared me.
I scoured the Internet looking for the sound equivalent to our coyotes, but I came up short. The closest thing I found was an audio clip at audiosparx.com. Scroll to the bottom of the page and it's the next to last audio clip. Pay attention to the screaming after the barking, and imagine that times twenty.
It sounds like a village of screaming demonic women.
