Song of the Coyotes

I'm not sure why I clicked on this video--curiosity, I suppose. 

In my north Florida neighborhood, I have spotted a lone coyote once or twice on my morning walks, but never heard them.

Or so I thought.

Sing, baby sing!

After listening to the video, I realized that I have heard the song of the coyote--many coyotes.
It begins around 26 seconds in, when a bunch of coyotes start up their noisy chorus. I have heard this frightening, thrilling sound just outside my house and mistaken it for a dog fight. I'm love dogs and was upset at the thought of one being hurt.

Now that I know coyotes were to blame, I don't know whether I should be comforted or troubles. 

Maybe a little bit of both.
