Birds primarily rely on sight and sound to evade predators. We know that ruffed grouse are far more jumpy in high winds because their hearing is impaired. Living in dense cover has heightened their dependence on sound. In my opinion, their sense of hearing is often greater than sight. When we factor in transgenerational stress inheritance, we gain insight into sound’s profound impact on ruffed grouse hunting. 

No matter how good the dog’s work may be, its bell’s jingle alerts grouse. The birds understand the threat, beginning evasive movements well before a dog has a chance to catch scent. Between scenting conditions, bird locations, and weather, a million variables stack up against us in unknown ways. These odds are daunting enough to dissuade us from adding another variable that would put a dog at an inherent disadvantage. However, the efficiency of killing is far from the pinnacle of the true love of grouse hunting, and interpreting the language of a dog bell is often part of that joy. 

Bells, talking, and walking through cover all impact grouse well before contacts are made. This is no new theory, and while I have experimented in recent years by leaving the dog bell in the truck, one can go back as far as the late 1800s to read from our forefathers on the topic of grouse and sound.
