Whitetail deer aren't that articulate, yet they are very curious animals. They make about three general sounds. Most their sounds are variations of grunts, snorts and bleats. They apply the sounds in different levels of sound pitch and intensity to express general feelings. In essence, these animals react to whitetail deer calls mainly because of their curiosity, mating and another male deer's encroachment. What they say may comprise of, "This way," "I need help," "Leave me alone," "I'm not happy" or "I am ready to mate."
Knowing which calls that trigger unique reactions which get you in the game, along with generating the good hunting call with the perfect routine gives you the prospect to shoot.
Whitetail deer really are sociable wildlife, and they are curious about different deer. In the Fall, when the buck deer tend to be in bachelor groupings, and does are with their young are in their family groups, call sounds may encourage reactions of interpersonal curiosity. Bucks usually are attracted to other male deer, as well as does tend to be intrigued in visiting female deer that come into their areas. Short, monotone "social" buck grunts can excite curiosity in bucks, and fawn or doe bleats will certainly draw in female deer. Buck deer tend to be interested about other bucks sparring in their area, thus light horn rattles can work at this time.
When the rut approaches, male deer are a lot more hostile and antagonistic to other male deer of similar size and stature. We call this a territorial reaction, because I really do not think a buck draws a "line in the sand" and guards a particular area during the rut. Some will react to male whitetail grunts, but far more hostility. White tail bucks come to explore other bucks during this time period, therefore bucks grunts continue to work.
During this time, much more aggressive calling sounds can be successful. Snort-wheezes, irritated grunts and aggressive horn rattling will bring in dominating big bucks in ideal scenarios, but these sounds can also intimidate and scare away smaller deer. Be careful with those deer hunting calls.
Right after most female deer get to the height of their estrus fertility cycles, the rutting is in full action, and male deer tend to be a lot more curious about does instead of other male bucks. Doe bleat calls become the most effective deer calls, with years of practice you don't need a caller and you can make your own sounds.
