As mentioned already, concealment requires camouflage clothing that blends reasonably well with whatever the background is. My brother uses a ghillie suit with lots of dark green and browns. It is an amazing piece of camouflage in the forest or in scattered juniper but in the desert, it stands out like the proverbial sore thumb. Choose something that is the correct hue for the area youíre hunting. A pair of Carhartts and a plaid shirt of the right hue is more effective camouflage than the latest pattern with the wrong shades of color for the hunting area.
Break up your outline or silhouette by sitting in front of something. A single bush or Yucca plant can provide enough backdrop to make you invisible to a predator if you ensure your head and shoulders are below the top of the bush. Keep the perspective of the incoming predator in mind. An animal coming up slope may cause the hunter to become skylined as they approach from below. And, while we are discussing skylines and outlines, be sure to use any cover you can when cresting a skyline heading for your stand. The top of the hill is not the place to stop for a meeting with your hunting partner or to make final decisions on your set-up location. Move quickly below the top of the ridge before stopping. The physiology of the coyote eye makes it unlikely that they have acute distance vision but a skylined form is much easier for animals to pick out.
Those same eyes that donít see well at long distance pick up quick, jerking movements easily. So, whether on stand or approaching your stand, avoid quick movements or gesturing with your arms or shooting sticks. It is rare that anyone stays absolutely still on stand. In most situations, some movement is required to see approaching predators. Concealment requires those movements to be slooooow. Quick movements by hunters result in many predators keeping their skins intact rather than ending up in the fur shed. Cats are even more acutely aware of movement. They are also more methodical approaching your stand. Cats are stalking the sound they hear. They are very visual, making concealment and slow moves even more imperative than with coyotes.
And, before leaving the area of movement and concealment, whenever possible make your moves while the predator is moving. A stationary animal has a much better chance of seeing movements around it than an animal in motion. If the coyote is stopped and scanning the area, donít move!
