Quick Answer
Specific calls work better on rivers due to the unique acoustic properties of water, which allow calls to travel farther and be more easily heard by waterfowl. Calls that mimic the sound of water, other ducks, or predators seem to have the most success. These calls help ducks locate water sources and potential threats.
Choosing the Right Calls
When hunting ducks on rivers, it’s essential to use calls that can be heard by waterfowl over long distances. Research has shown that duck calls that produce a frequency range between 1.2 and 1.5 kHz are most effective for long-distance communication. Calls like the Federal Duck Call or the Mallard Call produce these frequencies, making them excellent choices for river hunting.
River Call Techniques
To make your calls more effective on rivers, focus on using a steady, consistent tone that mimics the sound of a duck swimming or diving. Practice calling in a smooth, even cadence, taking care not to make sudden changes in pitch or tone. Experiment with different call positions and angles to find the one that produces the best sound quality and travels farthest. For example, holding the call about 6-8 inches from your mouth and aiming it downwards can help project the sound across the water.
Call Sequences and Timing
When using calls on rivers, it’s crucial to vary the sequence and timing to keep ducks from becoming habituated to the sound. Try using different calls in succession, such as a soft quack followed by a loud mallard call, to create a sense of uncertainty and keep ducks engaged. Varying the interval between calls also helps maintain the ducks’ interest, so experiment with different timing patterns to find what works best for your specific hunting situation.
