Companion Bird Nutrition: What Parrots and Other Birds Actually Need

The science of companion bird nutrition, why seed-only diets cause serious welfare problems, and what evidence-based feeding looks like for parrots and other birds.

Key Facts

Seed-only diets cause vitamin A deficiency and fatty liver disease in parrots
Many parrot species in the wild eat a diverse diet including fruits, vegetables, nuts, and insects
Commercial pellet diets formulated for specific parrot species provide better baseline nutrition than seeds
Fresh vegetables, fruits, and cooked grains should form a significant part of parrot diets
Obesity is a major health problem in companion parrots fed high-fat seed diets

Welfare Considerations

Companion bird nutrition is one of the most common welfare failures in pet bird keeping. The traditional pet shop recommendation of an all-seed diet is now known to be seriously deficient for most parrot species. Seeds are high in fat and low in vitamins, particularly vitamin A, leading to deficiency diseases, liver problems, and shortened lifespan. Parrots in the wild eat a diverse, seasonal diet that is difficult to replicate in captivity but can be approximated with pellets, fresh produce, and limited seeds as treats. Understanding the species-specific nutritional needs of companion birds is essential to their welfare.

What You Can Do

Transition seed-eating parrots to a pellet-based diet with guidance from an avian vet
Offer a wide variety of fresh vegetables and fruits daily to companion birds
Consult an avian veterinarian with specific knowledge of your bird species
Join reputable avian keeper communities for evidence-based feeding advice
Avoid feeding avocado, chocolate, onions, or alcohol to birds — all are toxic
