Behavior/Health Concerns:  Obesity is an important concern for the double yellow-headed Amazon’s health. Provide your pet bird with a balanced, low-fat diet supplemented with plenty fruits and vegetables as well as foods high in natural beta carotenes, such as carrots, beets and sweet potatoes. Double yellow-headed Amazons are susceptible to vitamin-A and calcium deficiencies, psittacosis and poxvirus infections. Double yellow-headed Amazons can be territorial during breading season according to Diana Holloway, former president of The Amazona Society. Female double yellow-heads are often more girlie, demonstrating nesting behaviors such as hiding in the sofa or kitchen cupboards, while males are more gregarious and tend to strut around, said Holloway.
