Whether I make a call stand or whether I'm stalking in on a bedded coyote that I see.
I try & use the same tactics. Come in crosswind or quartering in from, an up-wind angle.
Say for example;
1.Wind is from the North[12:00 position]
2. Seen, coyote or call area, is at the 12:00 position.
3. I'll come in at the 10:00 or 2:00 position. Angling, if you will, towards my intended target/[coyote or call area].
Reason being...A coyote, that is "bedded" will be facing a down-wind position, looking, listening, & listening, scenting their up-wind.
I come in from their visual blind-side[10:00 or 2:00]. As I'm up & across their wind. Thus a bedded coyote is facing away from me. Doing so, much of my walk-in noise & or scent. Is carried parrallel & down-wind of my target[ call area & or coyote].
I'll park quietly, generally 3/8-1/2 mile away angled up-wind from my target. I slowly & quietly work my way towards my target. If I'm calling, I try not to get any closer than a 1/4 mile away from the cover area, I plan to call.
I also use any available cover & or hills & draws to conceal myself as I go. Stay hidden, stay quiet & watch my wind.
I also watch where & how I step. Especially if the ground cover is "loud". Step softly, walk methodically.
Coyotes are most often on the down-wind side of any structure/[hills, trees, fencelines, ect]. Adjust accordinly.
Here is a prime example, below. Pic is facing NorEast. Coyote useing a North-South fenceline to cut the wind. Wind is stout from the SouEast. Coyote is facing a Southlery direction.
You add ground cover or timber to this pic. Changes very little.
99% of the time, a bedded coyote or fox, is facing a down-wind direction, useing any available structure to cut the wind. I could've easily snuck in, from the NorEast[blind-side] of this bedded coyote & killed her. But gave her a free pass, that day.
