I have not many experiences about coyotes but foxes here have started to follow the humans because their area is getting smaller, on the other hand they can feed perfectly on human dumping sites. So they live now in cities as well. In these circumstances it can happen that the animals no longer act that shy as they would in a complete wilderness.

I have seen one evening a coyote in Yosemite. It came out of the woods on the parking lot -it was evening but quite some people were around- stood still, looked around and went back slowly without showing any signs of panic.
