You can't talk about deer in Pennsylvania without someone bringing up the coyotes that eat some of them.
But how big of an impact do they have?
Pennsylvania hasn't studied the issue since about 2000, but another state did more recently, albeit in a backhanded kind of way.
Researchers in Michigan this past winter looked at predation on white-tailed deer in the Upper Peninsula, largely to see how many deer were being eaten by the roughly 700 wolves that live there. What they found is that coyotes and bobcats, in that order, eat more deer than wolves do. Hunters were the third-biggest cause of mortality among deer, with wolves fourth.
