Coyotes called to the bow is a tall order.
If there aren`t alot of people calling to them in your area, it will make it easier to find out what works best for your particular area.
Where I live, the traditional rabbit distress call
is almost totally inneffective now. There are alot of hunters using calls and few of them are doing it correctly. They are providing a good education for the already wiley coyote.
STEALTH is the key. Noise and movement can end the hunt before it gets started. Call softly at first, and increase the volume after you have gotten no response. Always assume a yote is close by, cause they probably are.
As already stated, scent is your enemy. I believe a coyote has a nose far superior to almost any animal. You won`t hide your scent from him. You have to shoot him before he smells you.
As with any hunting endeavor, advice helps, but you must do most of the learning yourself if you don`t have someone to SHOW you.
My advice would be to first call SOFTLY.(for thick cover) Expect a yote to get the wind in his face when he responds to your call. Expect long range shots.(30 yds or more) A yote can come from 400 yards and know within a few feet where the sound originated. When he gets to thirty yards or so he will know he should see what he is coming for, thats where
a small group of feathers gently moving from the wind will help. I would highly suggest a back up gunner, someone who can shoot.
Best of luck, I have tried many times to call a yote and take him with an arrow. I have been close
and even drew blood, but ended up tracking in the snow and finishing what I started with a .22 mag.
