Why doesn't the quetzal survive in captivity?

The quetzal struggles to survive in captivity primarily due to its specialized dietary needs, which include a diet rich in fruits, particularly avocados, and insects. Additionally, these birds are highly sensitive to stress and require specific environmental conditions to thrive, which are difficult to replicate in captivity. Their natural behaviors, such as nesting and flying in dense forest canopies, are also restricted in a captive setting, leading to mental and physical health issues. Overall, their unique ecological and behavioral requirements make successful captivity challenging.
