Is it okay to keep a cardinal as pet?

Keeping a cardinal as a pet is generally discouraged and could be illegal in many areas. Cardinals, and most wild birds in North America, are protected under the Migratory Bird Treaty Act, which makes it illegal to capture, kill, or possess them without a permit. Additionally, cardinals require specialized care and diet, so keeping them as pets can be challenging and may have adverse effects on their wellbeing. It's best to observe and enjoy cardinals from a distance in their natural habitat rather than keeping them as pets.
