I say I caught? LOL
and no, in the close to 2000 coyotes I've caught, not once did i see any of them quickly burying something as I drove up....................

but more to the point, I'm in the hayfields from April to late October- just about every day- and I toss 1000s of gophers in these fields- I see countless times, where coyotes eat these gophers & play with these gophers. and never have I seen one buried.
and I trap around countless compost/dead piles- and again, I see where they EAT and PLAY- but again, no holes with morsels of meat in them.
and have many carcass piles out and about- many i pass by each week a couple of times- and again- I see what i see.
think about it- do you really think an animal the size of a coyote, is going to take bite sized pieces, and bury a piece here, a piece there? no- canines gorge when feeding (when hungry) and return until the food source is gone (and long after if a big source, but thats another story)
I HAVE seen many times coyotes digging- and what does their digging look like? a trapper made dirthole? not hardly.
I'm not saying coyotes don't dig holes- that would be absurd- what I AM saying ,is that trappers dirtholes, made with the thought you are going to "imitate" a coyote-simply doesn't add up when looked at compared to a co yotes habits Coyotes dig, look into holes for FOOD- holes equate resting spots, burrows, dens and even yes catches made by SMALLER animals-
and back to the original point-a coyote IS going to investigate holes/with odors- and the more bells and whistles you give him, the longer he is going to stay its why remakes work so well- the entire set is satutated with GLAND odors, whether from urine or feces or just plain body scent
