Quick Answer
Cow calling mimics the sound of a cow elk in estrus, triggering bulls to respond and approach. Use a bugle tube or open-throat diaphragm call to produce high-pitched cow sounds. Start with soft, gentle mews and chirps to simulate a cow in the area. Periodically add estrous cow sounds (the 'hernia sound' - a distinctive high-pitched vocalization). Combine cow calls with bugling: call softly to locate bulls, then respond to their bugles. Use cow calls primarily during the rut (September) for maximum effectiveness.
Understanding Cow Elk Vocalizations
The Language Of Cow Elk
Cow elk make various sounds throughout the year, but rut-related vocalizations are what attract bulls. The primary sounds are:
Mews: Short, high-pitched sounds that cows use to communicate with herd members and bulls. Mews signal general contentment and presence.
Chirps: Softer versions of mews, used for close-range communication. A chirp might indicate interest in a nearby bull.
The hernia sound: A distinctive, high-pitched sound that female elk make during estrus, signaling reproductive availability. This sound triggers strong bull responses.
Understanding these sounds and when cows produce them helps you call more effectively. During the rut, cows are more vocal, particularly during estrus. Outside the rut, cow calls receive minimal response.
Bull Response To Cow Calls
Bulls respond to cow sounds with bugles, signaling their location and establishing presence. A receptive bull will move toward cow sounds to determine if the cow is available for breeding. This behavioral trigger is the foundation of effective cow calling.
Cow Calling Techniques
Selecting A Calling Device
Diaphragm calls (open-throat devices) allow hands-free calling and can produce a range of cow sounds. Hunters place the call against the roof of the mouth and use breath to produce sounds. Learning curve is steep, but experienced callers can mimic cow elk quite convincingly.
Bugle tubes (simple hand-held tubes) are easier to learn than diaphragms and produce excellent high-pitched cow sounds. Many hunters use bugle tubes for cow calling because the technique is intuitive.
Box calls and other devices can also produce cow sounds, though they’re less commonly used for elk calling.
Producing Cow Sounds
To produce a mew, make a short, high-pitched sound that rises and falls in pitch. Think of a pained sound (“meeeee”) that’s not as loud or sustained as a bugle. Mews are gentle and frequent during cow calling sequences.
For the hernia sound (estrous cow call), produce a distinctive high-pitched wailing sound that sounds almost strained or pained. This sound is extremely attractive to bulls and should be used periodically in calling sequences to trigger bull responses.
Practice these sounds extensively before season. Record your calls and listen critically. Poor cow calling can actually push bulls away if they detect unnaturalness.
Calling Sequences
Start a calling sequence with soft mews and chirps, establishing a cow’s presence without aggressive vocalizations. Call every 30-60 seconds. If a bull responds, stop calling and listen to his bugle to determine direction and enthusiasm.
Once you locate a bull, match his response pattern. If he bugles frequently, call more frequently. If he seems distant and cautious, call less and space out calls more. Calling too much can make a bull suspicious.
Periodically add an estrous cow call (hernia sound) to trigger stronger responses. This call is most effective during peak rut when bulls are highly motivated.
Advanced Cow Calling Tactics
Combining Cow Calls With Bugling
Some hunters use cow calls exclusively, while others combine cow and bull calls. A common strategy is calling with cow sounds, then responding to a bull’s bugle with your own bugle. This back-and-forth dialogue can convince a bull that multiple cows are in the area, increasing his commitment to investigate.
Alternating cow and bull calls requires practice to make transitions smooth and natural.
Multiple Calls For Different Situations
Multiple cows are more attractive than a single cow, so some hunters carry multiple calling devices to simulate a small group. Calling on both a diaphragm and a bugle tube simultaneously (or rapidly switching between devices) can create the impression of multiple cows in the area.
Positioning During Cow Calling
Position yourself where you can see approaching bulls while remaining concealed. Cow calls bring bulls toward your sound, so having clear shooting lanes and good cover is critical.
Don’t call from obvious vantage points. Bulls know that cows shouldn’t be in exposed locations; calling from a ridge top might push bulls away. Call from slightly elevated but concealed locations near cover.
Wind Management
Wind direction is less critical during rut calling than it is with rifle hunting during non-rut season, but scent still matters. Position yourself so a bull approaching your cow calls doesn’t catch your scent before coming within shooting range. If possible, have the wind blowing toward your position.
Seasonal And Situational Adjustments
Peak Rut Calling
During peak elk rut (late August through mid-September), cow calling is extremely effective. Bulls are hormone-driven and respond aggressively to cow calls. Even poor calling can be productive because bulls are so focused on finding cows.
Pre-Rut Calling
Before rut begins, cow calling receives less response. Bugling becomes more important. Some hunters still use cow calls pre-rut, particularly toward evening when bulls are becoming more vocal.
Late-Season Calling
After peak rut (late September onward), bulls become less responsive to cow calls and more wary. Bugling becomes less frequent and less responsive. Some hunters abandon calling entirely in late season and focus on glassing and stalking.
Common Mistakes And Solutions
Calling Too Much
Over-calling pushes bulls away. Silence is often more effective than constant calling. Call to locate a bull, then space out calls and listen more than you call.
Ignoring Bull Responses
If a bull bugles in response to your cow call, stop calling and listen. The bull’s response pattern tells you his interest level and location. Silent listening is underrated in elk hunting.
Poor Calling Execution
Unnatural-sounding calls push away experienced bulls. Practice extensively. Record your calls and listen critically. Consider attending elk calling camps or workshops to improve your technique.
Not Considering Herd Dynamics
In areas with established bachelor groups or established harems, a lone cow call might be less attractive than an area with multiple cows. Understand herd structure in your hunting area and adjust calling strategy accordingly.
