Nutritional deficiencies are among the most common and preventable welfare problems in companion parrots, with seed-based diets causing widespread chronic health problems.
Nutritional welfare failures are pervasive in companion parrot keeping. The widespread belief that seeds constitute an adequate parrot diet is deeply embedded in traditional keeping culture despite decades of veterinary evidence to the contrary. All-seed diets are deficient in protein, vitamins, and minerals, causing chronic disease that shortens life and causes prolonged suffering. The very palatability of seeds to parrots makes dietary transition challenging but not impossible with appropriate technique. Avian veterinarians consistently identify diet as among the most common and impactful welfare issues they encounter. Owner education about species-appropriate nutrition is one of the highest-impact welfare interventions available for companion parrots.
