[Lizette]

• Don't use the same call all day long. Ducks tend to call more in the early morning and in the early evening. They more fervent in vocalizing at these times.
• Keep calls quieter in mist and fog because sounds travel farther but are more muffled.
• Change the volume of the call by holding the call in a gloved hand, as it will absorb some of the sound. For a louder and less muffled call, use a bare hand.
