Even the boldest coyotes are wary of humans. Wariness of humans is a very innate coyote trait. However, there definitely is a continuum as to HOW wary each individual coyote is, and this seems to be more innate than learned, based on what I’ve been seeing.
I’ve seen coyotes, beginning from when they were small pups, who will not venture out of hiding until it is totally dark outside and until there are no people at all around.
At the other end of the continuum, I’ve seen coyotes, again from the time they were small pups, not afraid to venture forward in broad daylight, albeit always at a safe distance, when people are out walking their pets. The coyote above, sunbathing at noon in an open space frequented by walkers and their dogs, is one such coyote. The coyote’s eyes appeared to be closed, though I bet one of it’s eyelids was kept open just a tad! The coyote would lift its head only occasionally as some walkers passed by within about 200 feet! When a walker and dog approached much closer than this, the coyote dashed quickly to the bushes, putting an end to the sunbathing session.
