It depends on the adults and the type of terrain they are in . I've found them in the sage brush , in the side of south facing cut banks , in old animal holes and out in the flats just dug down in another animals hole that they have cleaned out , cracks in the rocks . If they are laid up during the day time they normally will be where if you watch them for awhile before you shoot you will see them look at the den hole and when you do shoot one go to where it was laying get down to their eye level and often you will see the den hole and if you were quiet going in you may even see pups out of the hole playing . The grass will be mashed down by this time of the year around the hole from the pups being out playing and you will see puppy crap laying around and if you have a fairly good sense of smell you will smell them . Coyote dens tend to be cleaner then fox dens . Fox dens most times have a lot of dead things laying around them but coyote dens don't as a rule . But they still smell like a bunch of puppies and their crap . It won't be long now till early in the morning the pups and adults will be doing the sunrise serenade and if it's been an hour or so after they howled they will answer you howling or a siren but if you run a siren don't run it too long a minute or a little less and wear hearing protection they will howl back and let you know where they are and I have had adults come in towards the siren . but if you use the siren it's pretty hard to call then after wards till the next day . It is a way to locate them and then stalk them at times but set and wait to see if they show up to it for 20 to 30 minutes then go looking for them . They often will go to a high spot before they howl at the siren and it takes time for them to calm down if they don't come to it . As a last resort if you have killed the adults you can get the pups to howl by using a puppy in destress call real loud they will answer it by howling but you want to wait for them to go back to the den hole if you use that as they tend to want to scatter from that sound with out their parents . Tracking is my preferred method of locating the den as I walk quietly and then can get back aways and call the adults to me back away from the den then go in and take the den . As I have said before if you are too close to the den and this time of the year at 8:00 or 9:00 in the morning and you howl the adults will often slip out to 400 or 500 yards and display giving short howls and barking to try and get you to follow them away from the pups . That's just a quick over view but a good starting place and a lot to keep in mind during the excitement of the moment . Writing it down helps me to remember things so when I think I want to get excited I can keep my self calm .
