Birds sometimes make crunching noises due to health problems. These sounds can signal that your bird needs help. Watching your bird closely can protect its health.
Two common health issues that cause crunching noises are problems with the beak and teeth, and breathing troubles. Understanding these helps you care for your pet better.
