How does calling attract game birds and deer?

In the context of sport hunting, calling is a method that involves waiting in a concealed location and using either the human voice or a mechanical device to produce imitative sounds that attract game.1

For game birds such as ducks, geese, and wild turkeys, hunters use calls to simulate the vocalizations of their own species. In nature, birds utilize various vocal signals—often referred to as birdsong—to communicate for purposes such as attracting mates, establishing territories, or maintaining contact within a flock. By mimicking these sounds, hunters can draw birds into range, often using decoys alongside the calls to increase effectiveness.21

Calling deer is a traditional technique, particularly in regions like Germany and Austria. While the specific mechanics of deer communication are distinct from avian vocalizations, the principle remains the same: the hunter replicates sounds that the animal associates with social interaction or territorial behavior to lure the prey toward their position. This method requires the hunter to remain hidden, as the success of the approach relies on the animal believing the sound is coming from another member of its species.1
