Like others have said, I cover face and hands (plus the usual others) then set still.
Have had deer walk up to me, stair & size up the situation, not until maybe 10 feet do they get alarmed.
Maybe JCS271 could add his perspective here, think he likes to hide in cover, sit still, and not big on camo colors ??
Look up his awesome hunter of the month wolf kills, at least one was with a bow !!!
On the color issue, there have been some good studies on yote eye response, like:
yote eyes
that article is a bunch of pages back from the start.
from that article, my take is:
Yotes only discern yellow and blue color differences.
Green has equal intensity response as Y or B but it shows to them as shaded of grey to white.
Humans see a spectrum of ROYGBIV while yotes see only YYYWBBB
(Red, Orange, Yellow, Green, Blue, Indigo, Violet & White for yotes)
The yote sensitivity is six time greater in their limited spectrum vs humans.
The yote clarity is worse, ie yotes need to be 75% closer for positive ID vs humans.
Yotes are especially sensitive to small movements, think rodents..
