First and foremost, do not get frustrated or discouraged... Realize that there ARE "dry" spells from time to time. A coyote's mind is always on a full belly, but at certain times of the year "other issues" take a hand as well... At these times you may well find calls that howl, bark, and imitate another coyote will be more productive than calls of a prey species. Pup crys and squeals are most productive at this time also...... Take a day or two and spend it locating coyotes. Travel the area you plan to call, looking for tracks, scat, large dead animals, etc... Something you may try is driving the roads in your area in the evening and stopping every mile or two, turning off the truck and the lights, getting out, closing the door quietly, and using a howler. Howl, wait and listen a half minute or so, then howl again... Wait a couple of minutes to see if you get a response. If not, go a bit further down the road and try again. If you do get a response, then remember this location to call the next day... Do not try to call them in at this time. Just locate them... The next morning you can call these locations with a series of locator howls, pup squeals, or domain calls...... But don't get discouraged if you are not hearing vocal responses when you begin to call. Coyotes don't always vocally respond. Many times they will slip in quietly, or come running and you won't know they are there till you see them or hear their feet slapping the ground behind you. Other times they will bark or howl and not come in at all, or they may come in as a pack snarling, barking, howling, and slobbering... And remember, they DO have to eat, so you may try a bit of variety with the prey species calls. If you usually use the cotton tail distress, try a jackrabbit, or bird distress, or pup whines and crys, or even a grey fox distress... Mix things up. Try to throw something different at them. You really never know for sure what will work until you try it.... If the weather is particularly bad, or the snow deep, try calling the more sheltered, and thicker areas...along the creeks, in the valleys, the edges of wood lots, down along brushy saddles.... Here where I live there are timbered hills and valleys, and brushy creek and river bottoms to my south, and flat lands and prairie to my north... and I have probably called as many or more coyotes in the thicker stuff, shotgun country, than I have up on the flat lands. So remember, "Coyotes are where you find them."... If you go to the same places, give them a bit of time to rest. Rotate your locations. Let one area "rest" for a couple of weeks while you work others.... But the main thing is to not give up. Few things worth having ever come easy.

Good luck!
