Can Birds Eat Peanuts? Only Fresh, Unsalted, and Rarely

The risk: mold on peanuts

Lafeber places peanuts in its list of foods that are not recommended but sometimes fed without incident. The reason is contamination: moldy peanuts and peanut products, as well as corn and other cereal grains, can be contaminated by a toxin-producing fungus.

You cannot always see this kind of contamination. That is why the safest peanuts for a bird are fresh, from a recent package stored dry and cool, and why any peanut that looks or smells off should be thrown away. Peanuts left in a humid cage or a damp bag are the ones most likely to go bad.

Fat and the seed-picking problem

VCA explains that conures and other parrots often pick out one or two favorite seeds and nuts, such as peanuts and sunflower seeds, which are high in fat and low in calcium and vitamin A. Diets built on these can contribute to ill health and a shorter lifespan.

The Merck Veterinary Manual adds that excessive dietary fat in all parrot species, especially sedentary pet birds, leads to obesity and is linked to metabolic and heart disease. A few peanuts as treats are one thing; a seed mix dominated by peanuts is another.

Salted, roasted and coated peanuts

VCA lists very salty foods among things never to feed a bird, and advises avoiding processed foods and foods cooked with oil. Most snack peanuts are roasted in oil and salted, which rules them out.

Honey-roasted, candied and chocolate-covered peanuts add sugar and, in the case of chocolate, a real toxin. Lafeber explains that theobromine and caffeine in chocolate can cause tremors, seizures and death in birds at toxic doses. Peanut butter often contains added salt and sugar, and some sugar-free spreads contain xylitol, which Lafeber links to severe hypoglycemia in dogs.

How to offer a peanut safely

Choose fresh, plain, unsalted peanuts from a recently opened package. Some keepers prefer peanuts sold specifically for birds. Offer one, or a piece of one for a small bird, by hand or in a dish, and store the rest sealed in a cool, dry place.

Throw out any peanut that is shriveled, discolored, musty-smelling or from an old bag. If your bird drops a peanut into its water or a damp corner of the cage, remove it rather than leaving it to sit.

Foraging for food keeps pet birds busy, so tuck a small piece into a foraging toy or clip it near a perch so it has to work for it.

How many peanuts are too many

For a budgie or cockatiel, a small piece of peanut once a week is plenty, and many keepers skip peanuts for small birds altogether. For a larger parrot, one or two peanuts a few times a week as a training reward is a common limit.

Treats of any kind should stay a small part of the week's food. VCA recommends pellets as most of the diet, with fresh vegetables and some fruit. Peanuts fit only in the treat allowance.

When to call an avian vet

Call an avian veterinarian if your bird stops eating, fluffs up and sits on the cage floor, has diarrhea, or seems weak or lethargic, especially if it has been eating from an older bag of peanuts or seed. A bird that is eating poorly should be checked by a veterinarian to rule out illness.

For peanuts coated in chocolate, or for any suspected poisoning, call your vet straight away. The ASPCA Animal Poison Control Center at (888) 426-4435 and Pet Poison Helpline at (855) 764-7661 can also advise; a fee may apply.
