Do deer eat meat if they are really hungry?

ok today i was hiking in the woods in central new york. there was about 12 inches of snow on the ground and everything was frozen solid. i noticed alot of deer tracks, i also noticed that the deer were eating pine cones( alot of half eaten pine cones on the ground), this seemed unusual. anyways, i saw a blood spot on the ground in the snow, there were alot of deer tracks around it. i followed the tracks up the mountian to find a small intestinal track of a small animal it was about 4 inches in length presumably a rabbit, squirrel, chipmunk. so would a deer eat meat if it was really hungry, and if it wasn t a deer what could it be?
