Interesting reading about coyotes and deer.
Have y'all read or heard about the study out of Maine, I think? They surmise because of the behavioral differences between coyotes, and bears, bears have a much broader impact on the deer herds than coyotes.
Coyotes, as members of the dog family, chase prey running away from them. Deer, does specifically, have evolved to run from danger, leaving their semi-helpless offspring curled up, motionless, silent, while their flight draws away these canine predators. The does usually escape, and the fawns are not often detected.
The black bear, however, does not use it's legs to pursue the fleeing, fast running, adult. Bears use their noses, and have evolved the behavior of following that scent trail back the other way, often being rewarded with a tender, spotted, high protein snack, curled up, motionless, at the end of it. Bears are related to pigs. Pigs have much more sensitive sniffers than dogs. In fact pigs are used to locate truffles, they're so well versed at scent location.
