I howl at 0:08 secs, and the first coyote response is at 0:43 secs.

Two days ago I went up to call coyotes in a 14,000 acre block of the White Mountain National Forest. I spent a good 5-10mins voice calling (howling and yipping) before I got a response. It was right around dusk on a crisp clear evening. There was one solo coyote to the West of me, and a pack about 1/4mi to 1/2mi Southeast of me. I turned the volume down in the video during the parts where I howl because it was so loud it was clipping. Hope you enjoy, the power of nature is quite incredible.
