Actually, I would not be surprised if they do. They have very keen sense of smell and are very selective in what they eat. When we were doing "bite studies" with tame deer on the Kerr Wildlife Management Area in Texas, the observers noted that if they reached out to touch a plant to help them confirm it's identity, the deer would invariably come over and sample that particular plant (or that part of a shrub)--even if they had not observed the touching.
Did anyone get any idea that a deer could smell an unseen food source, growing crops let's say, from a great distance? I've noticed they'll show up in larger numbers than I'm used to seeing just when the milo starts to ripen.
