A cage bird, also known as a captive bird or pet bird, can be described by a variety of synonyms. A common term for a caged bird is avian captive, but other descriptions include feathered prisoner, incarcerated bird, or domesticated fowl. A bird that is raised for its singing abilities can be referred to as a songbird or a canary, while a bird kept as a companion can be called a parakeet, parrot, cockatiel, or lovebird. Regardless of the synonym used, it is important to remember that birds are sentient beings that require proper care and attention, including a spacious living environment, a healthy diet, and regular exercise and socialization.
