When I was at Penn State, I helped one of the graduate students who was doing a fawn study with the PGC using radio telemetry equipment. Coyotes took there toll, but black bears were really nasty on fawns. Bobcats took a fair number as well.

I found a fawn during PA's bear season in Nov that had been killed by a bobcat. It was killed right on the edge of one our food plots. On Mon it wasn't there... Tues I was in my stand and see it partially covered by leaves. Right at dark a big bobcat comes up to it, uncovers the leaves and begins feeding on it. I guess it killed it the night before. For their size, bobcats are pretty efficient predators... Too bad PA is so strict about shooting bobcats. They act like they are extremely rare. We got more bobcats than coyotes.
