There has been a lot of pressure on coyotes lately. Almost everyone has an electronic call nowadays, so most of the coyotes have heard most of the "normal" sounds. Try to go somewhere that is as far off the beaten path as you can. Get away from the usual calling areas that are more accessible to hunters. The further out in the boonies you can get, the better you should do. First of all, be as quiet as you can when driving into an area and getting to your stand. Stay as much out of sight as possible. Once you get set up, just sit and wait for 5 to 10 minutes before you start calling. My "standard" progression is to start out with a "soft" call (like Bay Bee Cottontail or crying kittens) at a low volume. After 4-5 minutes, I bump it up to a medium volume for another few minutes. Then I shut the call off for about a minute and go to a "medium" sound (like an adult cottontail) at a medium-low sound level. After 3-5 minutes, I bump the volume up to medium or even medium-high, depending on the terrain (if the area is really open, I call a bit louder). The next one I usually go to is the adult jackrabbit at a medium volume and then to Lightning Jack at medium to medium-loud. If nothing has come in at that point I switch to an "unusual" sound, like Lucky Bird or a Raspy Woodpecker or a raccoon fight. My last call is a coyote pup distress at full volume. Stay at your stand for at least 20 minutes, longer if you think you are in a prime location, even up to 45 minutes to an hour. If you get a shot, switch immediately to coyote pup distress at full volume. If your call has the FOXBANG technology, set it up to switch automatically. Hope this helps. Good luck.
