Companion parrots are frequently fed seed-only diets that cause serious nutritional deficiencies, with pellet-based and varied diets significantly improving welfare and longevity.
Parrot dietary welfare failures are pervasive and preventable: seed-only diets sold as standard parakeet and parrot food cause chronic malnutrition that manifests over years as immune failure, respiratory disease, and metabolic problems. Parrots fed seeds in the wild are eating whole unripe seeds with different nutritional profiles from the dried seeds sold commercially. The transition to pellet-based diets requires patience but produces dramatic welfare improvements. Veterinary parrot nutrition knowledge is improving but many practitioners still lack the parrot-specific expertise needed for dietary counselling.
