Keeping pet birds can be ethical as long as their needs are met in terms of proper housing, nutrition, social interaction, and veterinary care. It is important to ensure that the birds have adequate space to move around, access to a balanced diet, opportunities for mental stimulation, and regular check-ups by an avian veterinarian. Additionally, it is essential to research the specific species of bird being kept to understand their natural behaviors and requirements to provide them with a suitable environment. As long as these conditions are met, keeping pet birds can be ethical.
