I'm a ridiculously light sleeper and I can tune out coyotes real easy from hearing them almost every night growing up. Even when I lived right in the middle of town for a while I could still hear them sometimes if I was outside. They're everywhere.
They're like fucking ghosts too. I was deep in some thick woods one time and all the birds went quiet. I kept thinking I was seeing something moving out of the corner of my eye, I'd look, wouldn't see anything, and then it'd happen again. Finally, after like 10 times of probably looking straight at the thing, I saw a coyote blending in with everything perfectly. I stopped and had a smoke and while I was standing there, I noticed another one, then another one, then another one, then another one. They kind of congregated and all fucked off together totally silently. There were four of them probably doing laps around me for a good while and I never heard anything but my own footsteps.
