Late July and August can be very productive months as the pups are kicked out of the Den. Coyotes kill a lot of deer, so kill every coyote you can.
Don't over hunt a single area.
Use camo on your face and hands, earth tone clothes are ok, also camo on your gun.
I use a set of hand pruners and carve a place in a bush to break up my outline, sit on a fold up stool.
If legal in your state, put two cans of sardines in oil in single sock, use two socks hung 15 yards on each side of you. This will help mask your scent as the sardines put out more parts per million vs your scent.
Look back and forth with your eyes, not by turning your head.
Have a plan with your hunting partner, work the plan.
don't slam the car doors
when loading your gun, do so very quietly!!!
Don't talk on the way to your stand, whisper and use hand signals.
When you shoot, shoot sitting, don't stand up. When you kill one, start the stand all over again, expect multiples.
Reload your gun quietly.
When walking back to the truck, be ready to shoot as often more are coming in from miles out, don't talk loud with your partner.
Most important, watch the weather patterns.
Leading edge of a low pressure front is the best, and low pressure front on top of you.
Immediately after a storm may be good.
Do not hunt during a high pressure front, scout. All you do is educate coyote during a high pressure front or when barometric pressure is rising. I have a barometer in the truck. When the pressure is falling, hunt, hunt, hunt.
Watch the Solar tables for major and minor feeding periods, it is your Bible of when and when not to hunt. This along with the weather issues will be the key to your success. I can not stress the solar tables enough. There is an apt for I phones for this.
Always place the call facing into the wind, and watch your down wind side. Coyotes are scared to death of each other, they will circle down wind to see if they can smell the other coyote that has hold of the dying animal. Dominant coyotes may kill or injure coyotes from another territory or younger coyotes.
Use two pair of boots or shoes. One pair when you leave home to stop and get gas. Then when you start hunting, put on your hunting boots. A coyotes that crosses your track may smell gasoline for 30'.
Often a 12ga with extra full or turkey choke with 3" number 4 buck is excellent, depending on the terrain. Pattern your shotgun.
If you see a coyote coming in that is going to cross your track, kill him prior to him winding your track.
Hunting partners can make or break you, choose wisely. Loudmouths that don't take it seriously will kill your percentage, smokers hurt also. Hunting partners need to change shoes also.
Coyotes come in in various intervals:
4 minutes or less, they were within 300 yards of you when you started your stand
7 minutes, they are within 1/2 mile
15-30 minutes, about a mile out or more...watch your down wind side!
Coyotes have the attention span of a Nat. They may come across a rat, mouse, rabbit, other coyote scents that will detract them from your call, so keep calling.
We hunted Mexico for 12 years, killed a lot of coyotes. One thing that we learned that hunting on a full moon, hunt from 10am to 3PM. If you can night hunt, hunt before the moon comes up on a full moon. High pressure fronts kill all efforts except the dumbest of the yearlings.
Sardines are God's gift to a Predator hunter, we transported ours in zip lock plastic bags inside 1 lb coffee cans. When on competitive hunts, we made a drag out of a sock with sardines and oil, smeared a tad on the bottom of our boots, set watching our tracks, hopefully down wind side. When using a Drag, set up where you can see the trail you walked in VERY clearly. When using a Drag, hold a shotgun in your lap, with a rifle by your side. El cheapo Mossburg 500 with a Hastings .660 ported choke is a meat grinder at 40 yards with Rem #4 Buck.
Coyotes can clearly hear a call at 1 mile down wind, depending on terrain.
For hand calls, the simplest to blow is the Lohman Circe MVP-3 adjustable

and the Johnny stewart PC1. Both of these calls are closed reed. Open reed calls are hard for a novice to master unless you have been a duck hunter.
If a coyote is circling you a mouse squeeker will often bring them in running, but be aware that they can pin point your movement to within 1* at 1000 yards. I hold one in my left hand, can still blow the call while watching the coyotes reactions with my left hand holding the gun. They can hear a mouse squeeker at 400 yards easy in calm winds.

The above is Hard Core coyote hunting, take it to the degree that your interest and patience allows. Fools that think that this is coyote shooting will be sorely disappointed.
Fish and Game in our state put out a camera by a coyote den in the Spring, that pair of coyotes brought in 22 fawns that year.
