Companion parrots are commonly fed seed-based diets that are nutritionally inadequate, leading to deficiency-related welfare problems that are largely preventable with evidence-based feeding.
Nutritional deficiency in companion parrots represents a large-scale preventable welfare problem driven by outdated advice and persistent cultural norms around seed feeding. The appeal of seed diets to birds reflects evolutionary programming toward energy-dense foods rather than nutritional completeness. Transitioning parrots to species-appropriate pellet-based diets with fresh food supplements is one of the most impactful welfare improvements companion bird owners can make.
