Now about those calls. While deer make a number of different vocalizations, the most common is the grunt. It's not a loud or excited sound, but a simple grunt used to communicate with other deer. The sound isn't for any breeding purpose, as deer make it year round. Basically, it's just simple communication to let other deer know where a buck or doe is. Many companies make grunt calls that are effective for calling deer. Not only will most make the normal grunt mentioned earlier, but most can make the loud grunting sound bucks use to show dominance and even deep, guttural tending grunts. Tending grunts make bucks think the buck you are mimicking is breeding a doe, so will often draw passing bucks in to investigate. Does also grunt, but in a much higher pitch than bucks.
