Oh what a beautiful thing to witness! I'm envious!
We have a small pack of coyote in our neighborhood somewhere, as we can hear them communicating with one another on a nightly basis. Usually around 1:00AM while I take the dog on his last walk of the night I can hear them howling back and forth to one another in the neighboring woods. Years ago it would make my hair - and the dog's fur - stand on end every time. Now it's become a welcome and pleasant sound that I look forward to.
I must admit, though, that I'm glad I can only hear them, and not see them!
