Many pet birds love peanuts, and they can be a healthy treat when offered correctly. Peanuts provide protein, healthy fats, and B vitamins that support feather quality and energy levels. Parrots, macaws, and conures especially enjoy them as foraging rewards or training treats.

However, there is a significant safety concern: aflatoxin contamination. Aflatoxins are toxic compounds produced by Aspergillus mold that commonly grows on peanuts during storage. Even small amounts of aflatoxin can damage a bird's liver and immune system, and chronic exposure can be fatal. Always buy human-grade, aflatoxin-tested peanuts from reputable sources rather than bulk bird-store bins where quality control may be lacking.

Only offer unsalted, unflavored, and dry-roasted or raw peanuts. Salt is extremely dangerous for birds because their kidneys cannot process sodium efficiently, and flavored coatings often contain garlic, onion powder, or artificial additives that are toxic. Remove the shell if it looks discolored, dusty, or has an off smell, as these are signs of mold growth.

Portion control matters. Peanuts are calorie-dense, and birds prone to obesity or fatty liver disease, such as Amazon parrots and budgies on seed-heavy diets, should receive them sparingly. A few peanut halves two to three times per week is plenty for a medium-sized parrot.

Store peanuts in an airtight container in a cool, dry place or refrigerate them to slow mold development. Discard any batch that smells musty or looks discolored. When in doubt, skip the peanut and reach for a safer treat like a small piece of carrot or bell pepper.
