Where I hunt they are thick. The scent must be everywhere,so I think they are used to it. I can say though that when I see deer around my stand and the coyotes go to yipping and cutting up it does get their attention.

Deer around here get real jittery when a couple Coyotes pass through or hang around. They seem to be on the alert more.

I have seen deer come in right after coyotes on more than one occaision.  I am sure they are sensitive to them, but as stated...there is no where to go around here without them.

I think it depends on the deer and/or the situation...just like sometimes deer will hang up on a path I crossed or walked down, other times they will walk right down the trail I came in on.

Heard here and before that urine is urine regardless of species, and people wizzing in scrapes and stuff, so if that is the case, how's come professional trappers just don't take a leak at their trap sets?

Being a telephone man and back in the day when we fixed phones, I can tell first hand the difference of cat piz than dog piz in the air when entering a building.

Would be interesting to hear clinical information from someone in the scientific field  that could or would enlighten us on or if differences...

Hey, Zbone.  For those who think urine is all alike, I have one word: Asparagus!

The problem with trying to avoid sign of a coyote's passing is that coyotes REALLY get around.  Avoiding sign wouldn't leave the deer many places to be!

Generally speaking,  I'd have to vote yes!   Like many others have said already,  if they avoided EVERY instance of fresh coyote sent,   they would have NO place to go!  I am convinced the coyotes are that thick around these parts for certain.  Right up until about 5 years ago,  I would NEVER see coyotes on stand....NEVER!  Im still hunting the same half dozen stands that I have been the past 20 years around this area....stands that are scattered around 3 adjacent towns....and I see coyotes on the regular!  And I always see them AFTER the deer come through....and they are Following the deer traffic direction.  I now hunt coyotes specifically, after the deer season (yup,  theres a coyote season here!)
I believe that whatever mixing of deer and coyotes we observe,  is simply happen stance and on account of the fact that coyotes are VERY smart....and deer well, .....they ARE great survivalists!
Prey animals avoid predators....period!  Its the general rule thats gotta be close to a billion years old by now.

We also have to remember that the region and or type of coyote makes a difference in deer response as well. Our Eastern coyotes are from a line of wolf/ coyote interbreeds and are a bigger stronger animal generally. They will and do hunt in small packs and will and do kill mature deer occasionally. Iv' seen Eastern coyotes as large as 75 lbs. and some report larger specimens. They certainly do take their toll on the fawns. They thinned out or chased off my herd substantially.

I've got trail cams pics of coyotes and just a while later deer showed up and stayed. I would have thought that the deer would vacate the area but after seeing this same thing over the past 7 years or so, I think that deer seem to know  if the coyote is close by or not.

I doubt coyote scent is going to bother the deer. The likely reason you didn't see any deer on your morning hunt is that, even during a January warm up, northern deer in the middle of the Winter typically don't move much until dusk, when daytime temps are usually at their highest.

Not an issue in my world. I commonly see deer and coyotes within minutes of each other. There's nowhere the deer can go to avoid 'yotes anyway, as they occupy all areas.

I have seen coyotes hunt in very organized packs, and seen single coyotes call in others for help.
