Confining a canary is a common practice for pet owners, as it helps to keep the bird safe and healthy. Encaging a canary involves providing a secure, enclosed space for the bird to live in, such as a cage or aviary. This ensures that the bird is not exposed to any potential predators or hazards, and also allows the owner to monitor the bird's health and wellbeing. Additionally, confining a canary can help to prevent it from flying away or becoming lost.
