Do elk vocalizations carry farther at night or during the day?

Acoustic Properties of Night and Day

When elk vocalize, their calls are affected by atmospheric conditions, such as temperature, humidity, and wind. Research suggests that the speed of sound is approximately 343 meters per second (m/s) at 20 degrees Celsius, but this value can decrease by up to 0.6 m/s per degree Celsius increase in temperature. At night, the air is generally cooler, resulting in a faster speed of sound, which can carry elk calls up to 50% farther than during the day.

Effects on Archery Elk Hunting with Calls

For effective archery elk hunting with calls, understanding the optimal time for vocalizations is crucial. By taking advantage of the increased carrying distance at night, hunters can use calls to initiate bugling sessions or respond to existing ones over longer distances. This can be particularly useful in early morning or late evening hunts when elk are most active, and their vocalizations are more likely to carry over the landscape. A good rule of thumb is to start with a 120- to 150-yard (109-137 meters) distance, and adjust accordingly based on the wind, temperature, and elk behavior.

Techniques for Effective Call Use at Night

To maximize the effectiveness of elk calls at night, hunters should focus on clear, crisp, and well-placed vocalizations. This may involve using a call that mimics the natural bugle of a bull elk, such as a high-pitched “yeeeep” or a series of low, raspy grunts. It’s also essential to listen carefully for responses and adjust the call accordingly. By using the right call, in the right location, and at the right time, hunters can increase their chances of attracting elk and getting a shot during an archery elk hunt.
