Turkey Communication

An understanding of the different calls that turkeys use will help when you are trying to call turkeys. Turkey researchers have described as many as 20 different turkey calls. They fall into six basic categories: Agonistic, Alarm, Contact, Intent, Maternal/Neonatal and Advertising/Mating.

When a turkey becomes aware of danger it makes a loud, sharp Alarm Putt of from one to five notes that is used to warn other birds of danger; TUT, TUT, TUT. The call is a sign that a bird has seen a potential predator, and is usually followed by the bird running or flying away. Do not use this call when hunting turkeys.

Agonistic Calls

Turkeys make a number of soft Putts, Purrs, and Whines while feeding. These calls are referred to as agonistic (as in agonizing) because they help keep the flock in contact, while keeping them apart when their heads are down and they can't see each other. The birds are uncomfortable when they get too close; thus they are in agony, so to speak. When they make these calls they are saying, "This is my space, don't get to close." The Feeding Whine or Purr sounds like the call made by a feeding chicken; a soft errr. It may be followed by one or more Feeding Putts; a soft contented putt, putt. I use these calls shortly after I use a flydown cackle, to convince a tom that there are hens on the ground and feeding. I also use it on toms that hang up out of range, to calm them down.

Fighting turkeys use an Aggressive Purr that is louder and more insistent than the feeding purr; the call is often interrupted by flapping wings, kicking and neck wrestling. Other turkeys hearing a fight often come running to see which birds are fighting, and which birds win and lose. The loser often drops down in the flock hierarchy, leaving room for the birds beneath it to move up. Any bird that has a chance to move up in the hierarchy will do so. The sound of birds fighting will cause dominants and groups of toms, even hens, to come running, so they can see which birds are fighting in their area. I use this call to bring in dominant toms or hens when everything else fails. I've heard toms use a churrt - churrt as a threat. This is probably one of the most aggressive forms of an agonistic call.

Social Contact and Maternal/Neonatal Calls

Because the Contact Calls are used most often between the hen and her poults they are basically the same as the Maternal/Neonatal Calls. When turkeys use these calls they are saying "Here I am, where are You?" The contact calls of young turkeys are the Lost Whistle, Kee-Kee and the Kee-Kee Run. These are all high pitched calls that change as the young turkey grows.

The Lost Whistle is the sound very young birds make. It is a high pitched whistle; peep, peep, peep, peep. As summer advances the voices of the poults change and the Lost Whistle becomes the Kee-Kee; a lower coarser kee, kee, kee. It usually has three unevenly spaced notes in about a second, with each note .10 to .15 seconds in length. Many callers fail to recreate this call correctly by using only two notes, or by using up to five notes. Maybe the name of the call should be changed to the Kee-Kee-Kee.

As fall approaches the young turkeys begin to add yelps at the end of the Kee-Kee and produce the Kee-Kee Run. The Kee-Kee Run is the basic Kee-Kee followed by several yelps; kee-kee-kee, chirp-chirp-chirp-chirp. The notes of this call are unevenly spaced, with each note from .05 to .10 seconds in length. All three of these lost calls are used by the young to tell their mother they are lost and to trying to get back together. I use these calls in the fall, after I have scattered a flock.

Adult turkeys use many different yelps and clucks to keep in contact in different situations. Most Yelps are the same as the "Here I am, where are you?" call of geese and other flocking birds, which is used to keep the birds in contact with each other.

The Tree Yelp is often the first sound of the day, a soft, nasal, three to five note call performed while the birds are on the roost before daylight. It is a soft chirp-chirp-chirp ... chirp-chirp-chirp-chirp, or a variation. There are usually three to four notes per second, with each note being about .08 seconds in length. This call is used by a bird when it is telling the others it is awake and asking if there are other birds nearby and awake. This is the first call I use in the morning, to see if there are toms in the area and still on the roost.

The Plain Yelp is performed when the turkeys are within seeing distance of each other. It often consists of three to nine notes, all on the same pitch and of the same volume, with three to four notes per second, and each note lasting .08 to .10 seconds; chirp, chirp, chirp. I use this call when toms are up close, or within seeing distance of the decoys.

The Lost Yelp is much like the Plain Yelp but may contain twenty or more notes, and it becomes louder toward the end of the call. The bird's voice may "break" as it tries to make the call as loud as possible, which causes it to have a raspy sound. There may be from three to four notes per second, with each note lasting .10 to .15 seconds.

The Assembly Yelp is used by the hen in the fall to regroup the young. It usually consists six to ten or more evenly spaced yelps that are loud and sharp, with two to four notes per second, and each note lasting from .12 to .20 seconds. I often hear hens make a loud, long series of yelps while they are on the strut during the breeding phase. I am not sure if this is an Assembly Yelp or a Lost Yelp. But, I do know that toms often show up in areas where hens are making this call. I use Lost Yelps and Assembly Yelps to get a tom fired up on the roost, and to keep it coming once it is on the ground.

The Plain Cluck is used by turkeys to get the visual attention of another bird. It is primarily a close range contact call, again saying "Here am I, where are you?" A bird making this call wants to hear another bird make the same call so they can get together. It is a sharp, short sound, similar to the alarm putt but not as loud or as insistent; tut...tut. The notes of the cluck are often separated by as much as three seconds, which distinguishes it from the faster, closely spaced Fast Cutt. I often hear hens use several soft Clucks and Purrs while they are feeding. It sounds like putt, putt, putt, errr, putt .... putt, putt, putt, errr. I use this call when a tom hangs up nearby, or to stop it for a shot.

The Fast Cutt, or Cutting, is one turkey using the "Here I am, where are you?" but telling the other bird "If we are going to get together you have to come to me." It is a loud insistent call, and the notes are strung together in bursts of two's and three's, with about a second between bursts. It sounds like; TUT...TUT...TUT, TUT. TUT .TUT, TUT...TUT...TUT, TUT...TUT... TUT, TUT... TUT, or any variation of clucks. The rhythm is somewhat like the Flying Cackle, and I have used a Flying Cackle to get a tom to "shock gobble." I also use this call to bring in a tom that hangs up.

Flying Call

The Flying Cackle is the sound a turkey makes when flying up or down from the roost, or when flying across ravines. Many hunters have a difficulty with the correct tempo of this call. Actually, it's quite easy; the calling of a bird in the air is directly related to the downbeat of the wing stroke, it's when the bird contracts it's chest muscles and exhales, it's the only time the bird can call. If you are trying to imitate this call visualize the action of the turkey as it takes off, first with slow powerful wing beats, then faster, and tapering off slowly before gliding and landing. I often use this call to get a "shock gobble" from a tom before daylight, so I can locate the tree it is in. I also use it to get a tom to come off the roost in my direction.

Mating Calls

Tom turkeys Gobble to express social status, telling other males they are ready to fight to prove their dominance, and to attract hens. The Gobble is most often heard while the bird is on the roost early in the morning. Studies show that most gobbling occurs from about a forty-five minutes before to forty-five minutes after sunrise. Individual toms also call most frequently at this time. Gobbling is a means of long distance communication and the tom may expect the hen to come to him, if she is ready to breed. However, I often see toms arrive at the strut where the hens are already calling. Whether the toms are responding to the calling of the hens or not I am not sure. Use a gobble only when you are sure there are no other hunters in the area, because they may mistake you for a turkey.

Hens in the presence of a tom may Whine, causing the tom to begin strutting. The medium pitched single drawn out errr of the Whine or Purr may be used by the hen to get the male to prove how large, colorful and healthy it is. I use this call when toms are close, to convince them there is a hen nearby. It has been said that hens make a whut churr - whut churr when they are ready to breed, and a prrrt - prrrt while being bred.

Once the tom is near the hen it spends more time strutting; displaying its colorful head, fluffed up body, and spread tail to impress the hen. When hens are within visual distance the less audible sounds of the Spit and Drum can be heard and used to attract them. It's believed that both the Spit and Drum are vocalizations. However, after watching toms snap their wings open on gravel, and hearing a sound like a spit at the exact same moment, I believe that at least some of the sounds that hunters refer to as the Spit may be the sound of the wing tips snapping open or hitting the ground.

 

Turkey Call Research

Many hunters and turkey researchers have reported that a turkey's tail vibrates when the turkey drums. I do know that when peacocks display by fanning their tail they drum by vibrating the feather shafts of their tail together in what is called a "harmonic rustle." This made me wonder if the drum of a turkey is not also produced by some movement of the tail feathers vibrating together. When I asked Lovett Williams about this he told me he had heard an Ocellated turkey without a tail perform the drum, which suggests that the drum is not produced by the vibration of tail feathers. He was not sure how the bird produced the sound, or whether the spit and drum are vocalizations.

On April 14, 2000, I had the opportunity to observe two domestic penned toms, and to solve the mystery of how these two sounds are produced. Luckily the two domestic birds were extremely tame and allowed me to get close enough to hear both the spit and drum as close as 6 inches away. As I sat near the toms I could hear them inhaling and exhaling deeply, and noted that when the Spit was performed the bird opened it's mouth and expelled air. This Spit was often followed by the drum; a low volume, deep-pitched humming sound.

I noticed that the tom's body, especially the tail, vibrated when the drum was produced. When I put my hand on the bird's body I found that the chest (not the lungs) was inflated, suggesting that the birds have large air sacs beneath the skin of the chest region. This area was warm to the touch and I could feel it vibrate when the drum was produced. As a result of this I suspect that the Drum is produced by movement of the air within the sacs of the bird's chest. Because the Drum may be produced in the same way as the "booming" of a Prairie Chicken, it may eventually have to be renamed the "Boom." Groups of toms, and dominant toms, may respond to the Spit and Drum of other toms out of dominance. But, subdominant toms and jakes may be scared off, because they are afraid of being attacked by a dominant.

Gobbling

Gobbling is the tom's way of expressing dominance; telling all the turkeys in the area that he is ready to breed, and to fight for the right. Toms also use gobbling as a means of advertising to attract hens. Supposedly, the toms call to get the hens to come to them, but toms do respond to hen calling and will go to the hen. The advertising strategy of the tom changes once it is with a hen. Gobbling is used to attract hens from a distance. But, when the tom is within visual distance of the hen it begins to strut, relying on the color of its head, its expanded tail, and its puffed up body size to attract the hen; to prove it is the biggest, healthiest, most colorful male in the flock. This explains the dimorphism (the difference in coloration, size, or antler growth) in many animals. The strongest, healthiest male with the most coloration or largest rack, attract more females, breeds more females and passes on its traits to the offspring.

I don't doubt that toms gobble to get hens to come to them. But, during my research I found that the hens were often in a feeding/strutting area first, often using the adult version of the lost yelp, then the toms showed up, gobbling as they came. Once the toms saw the hens they usually started strutting and pursuing the hens. Only then did breeding occur. I believe that in many instances the toms respond to the calling of the hens, not the other way around.

My studies show that peak gobbling dates may vary as a result of the amount of light, weather, age and social status of the males, how many males there are in a group, how many males there are in an area, the willingness of the hens to breed, and the hunting pressure. Before we go further let's discuss how some aspects of turkey behavior affect gobbling activity.

Gobbling In Response To Sound

Tom turkeys often gobble in response to loud sounds other than the calling or gobbling of another turkey. They have been known to gobble in response to thunder; and to the call of an owl, a coyote, an elk, a dog and a Pileated woodpecker. This response to loud sound other than turkey calls is referred to as a "shock gobble." In a study conducted by Schleidt, it was found that toms were most likely to respond to sounds in early April, and less likely after that. This may be one of the reasons there is often less gobbling during the later portion of the breeding season.
