Check the tracks...If the tracks are checking out all the brush piles then that coyote is hunting and may be in the area.. You can call it in. if the tracks are going from Point A to Point B....The coyote is traveling and could be just passing through the area.....
Remember Coyotes like deer have their own core areas...Now if you could find just where the Core area is in relation to the tracks.. You might be able to sneak in before sun up and catch it when it returns back to the core area for safety...Where are Core Areas usually? swamps, and along rivers and streams......
