I have a slightly different view on the senses theories.
The coyote makes his living utilizing all his senses.
Can you fool him? Of course you can or we wouldn't be hunting him.
So which senses can you fool and how are you planning to do it?
All his senses are keen and are used all the time everday to survive from predators and to feed himself.
When a domestic dog can be conditioned[trained] to smell drugs hidden inside a drum of dieasel fuel, I'm skeptical that all the smells associated with a human can be masked, disguised or eradicated to the extent that it would fool a coyote. It may be possible in something like a Hazmat suit, but for our practical purposes, I doubt it can be done.
His sense of hearing is easier to fool. We do it all the time with the calls we use. So in spite of the fact that he can hear at very long distances, as long as he does not associate the sound with "Danger", he can be fooled. His advantage here is that he
can hear at very long distances, so any 'human' sounds may activate the flight response in mr. coyote.
When it comes to "setting up" and camo, I think you have to seperate the coyotes excellent eyesight from the information this provides him to deal with the situation.
I'll try to explain. When I'm at gunshows, selling hunting gear, I'm always wearing a ghillie suit [because I sell them]. Several, [hundreds] of times over a weekend, I have people come by and say "I didn't see you there." Unbelievable!!!! Someone who is likely carrying a firearm in the field cannot see a large man in a ghillie suit from mere feet away. /ubbthreads/images/graemlins/smiliesmack.gif Now of course what they mean is "great camo". /ubbthreads/images/graemlins/grinning-smiley-003.gif
Why is it great camo?
If I am at a show in a ghillie and have the face mask on and the hood pulled up, sitting in a chair, not moving, I have had people pick up a call from my table and jump when I ask "What do you think of that?"
Again they have seen me, but the ghillie does what I believe good camo should do. It fools the eyes into telling the brain, "There is nothing here of interest, Move along"
Is this theory viable? I have seen a magpie land on the boot of a guy that was sitting on the ground in a ghillie suit. For those of you that aren't familiar with magpies, they are similar to a crow and possibly smarter. /ubbthreads/images/graemlins/shocked.gif
This thinking allows me to hunt in the terrain I have to deal with here. No cover!!! Flat wide open spaces.
I sit in the open , usually on the highest point around, and am perfectly confident that I can get coyotes into gun range.
Here's a couple of pics to illustrate my point.
This one is from 100yds.
And this one is from 50 yds.
I managed to get my wife to pose in the ghillie for these pics. They were taken on a large open field on the edge of town.
Being seen doesn't have to mean being busted.
I almost never set up in any kind of cover. I'd rather be in the open watching the bushline or hedgerow, and allow the coyote to use the cover to approach , feeling confident.
This is just another POV and may not apply to the areas you hunt.
