There are two situations like this.
Wild coyotes coming around human infrastructure, that don't normally do so, is the first. The scents are like bathwater. Starts out hot and cools off as time goes on. A coyote will have a great situational awareness of humans and other threats if it encroaches on an area where humans are known to be. They spook easily and are prone to times of day when human activities are less...Like at night.
The second situation is when coyotes become conditioned to human presence by prolonged exposure to humans.
Again, their senses are not really diminished, they are still coyotes. But the conditioning of human presence being not so much of a threat as much as the reward they get from the close contact around humans overrides the natural caution a wild coyote possesses. If there is no perceived danger, and they get a full belly every time they are around humans, that fear ceases to exist. A way more dangerous situation than the first scenario from both the coyote and human perspective.
I like this answer... I also believe they don't get "desensitized" but their behaviorism is based on learning through interactions within their environment-territory... especially when that territory overlaps urban or suburban areas.. I like the "bath water" analogy.. Coyotes around my house learn through interaction with me that it is hazardous for their health to stick their head up during daylight... Those that don't end up hanging on a fence... Even if you was hunting in the city limits the wind is still important, like shed hunter said: "...have the ability to distinguish between lingering human scents and the scent of a human that is actually nearby"
