Can Birds eat Potatoes?

Updated Jun 2026
Feed With Caution

Cooked plain potato only — raw and green potato are off the table

Birds can eat small amounts of plain boiled or baked potato flesh without obvious harm, but this comes with real caveats. Raw potato starch is poorly digested by the avian gut and may cause gastrointestinal upset, while solanine — concentrated in the skin, eyes, and any green areas — poses a genuine neurotoxic and gastrointestinal risk even in modest quantities. Birds are considerably more sensitive to solanine than most mammals, and because their body weight is so low, even a small piece of green potato represents a meaningful toxic dose. Fried, salted, or creamed potato preparations add fats, sodium, and additives that compound the risk further.

Severity
Moderate
Toxic dose
Solanine toxicity in birds is reported at approximately 1–2 mg solanine per kg body weight; green potato skin can contain 200–400 mg solanine per 100 g, meaning even a few grams of green peel is clinically significant for a small parrot or budgerigar.
Onset time
30 minutes to 4 hours after ingestion
Treatment
Remove access immediately; supportive care (fluids, warmth); contact an avian vet or poison helpline urgently if solanine exposure is suspected.
Feed Responsibly

Moderation Is Essential

Potatoes should only be offered to birds in small, infrequent amounts. Follow the safe feeding guidance and watch closely for any reactions.

Why are potatoes a caution food for birds?

Potatoes

Potatoes — birds.

Potatoes belong to the Solanaceae family — the same botanical group as tomatoes, eggplant, and deadly nightshade. All solanaceous plants produce glycoalkaloids as a natural defence against insects and herbivores. In potatoes, the principal culprit is solanine (and to a lesser extent chaconine), which inhibits acetylcholinesterase, disrupting normal nerve signal transmission. Birds have a relatively fast metabolic rate and a compact digestive system, which means toxins can be absorbed and distributed through the body more rapidly than in larger mammals. A budgerigar weighing 30–40 g or a cockatiel at around 90 g has an extremely small margin before a toxic dose becomes a dangerous dose.

Cooking significantly degrades solanine — boiling removes up to 60–70% of the alkaloid content from the flesh, which is why a small cube of plain boiled potato sits in a very different risk category from a raw chip. However, cooking does not eliminate solanine from the skin or eyes, and peeling alone is insufficient if the flesh beneath is green. Beyond solanine, raw potato starch forms resistant granules that the avian digestive tract cannot efficiently break down, potentially leading to fermentation, bloating, and loose droppings. For companion birds such as parrots, cockatiels, budgerigars, canaries, and finches, the safest rule is: if it isn't plainly cooked, peeled, and free of any green colouration, it should not be offered.

Green potato = genuine danger for birds

Any potato with green skin or flesh must be kept completely away from birds. The solanine concentration in green areas is many times higher than in normal flesh, and the toxic dose for a small bird can be reached with just a few grams of peel.

Symptoms & progression

Gastrointestinal signs (onset within 1–2 hours)
  • Regurgitation or vomiting
  • Diarrhoea or loose, watery droppings

  • Ataxia (uncoordinated movement)
  • Laboured or open-mouthed breathing
  • Bradycardia (slowed heart rate)
  • Collapse

Dose & severity

The table below outlines realistic portion guidance for plain, cooked, peeled potato flesh offered to companion birds. These portions assume the potato is fully cooked (boiled or baked), unpeeled sections are removed, there is no green colouration, and absolutely no salt, butter, oil, or seasoning is present.

Small birds (budgerigars, finches, canaries)
Body weight ~15–50 g
1–2 small pea-sized pieces, once or twice weekly at most
Any more risks displacing balanced seed or pellet diet; zero tolerance for raw or green potato at this size
Medium birds (cockatiels, lovebirds, conures)
Body weight ~80–150 g
Up to 1 teaspoon of diced cooked potato, 1–2 times per week
Treat as an occasional supplement, not a staple; ensure variety with proven-safe vegetables
Large birds (African Greys, Amazon parrots, cockatoos)
Body weight ~300–700 g
Up to 1 tablespoon of plain cooked potato flesh, occasional treat
Even at this size, raw or green potato must be avoided; excess starchy foods contribute to obesity
Raw or green potato — any bird, any size
All species
Do not offer
Solanine content makes raw and green potato unsafe regardless of bird size

What to do if your bird has eaten potato

  1. 1

    Identify what was eaten immediately. Determine whether the potato was raw, cooked, or green-tinged, and estimate how much the bird consumed relative to its body weight. This information is critical for any vet assessment.

  2. 2

    Remove all remaining potato from the enclosure. Do not leave any access to further pieces. Place the bird in a warm, calm environment and observe closely for the next one to four hours.

  3. 3

    Contact an avian vet or poison helpline if raw or green potato was eaten. Call the ASPCA Animal Poison Control Center (888-426-4435) or your nearest avian-experienced veterinary clinic straight away. Do not wait for symptoms to appear — solanine toxicity can progress quickly in small birds.

  4. 4

    Monitor droppings and behaviour closely. Even if only plain cooked potato was eaten, watch for loose droppings, fluffed feathers, regurgitation, or reduced vocalisation over the next 12 hours. Any deterioration warrants a vet call.

  5. 5

    Do not induce vomiting. Birds have a different digestive anatomy from mammals; attempting to induce emesis at home is dangerous and ineffective. Leave any decontamination decisions entirely to a veterinarian.

Safe alternatives

If you want to offer your bird a starchy or vegetable-based treat that carries none of the solanine concerns associated with potatoes, these options are well-supported by avian nutritional guidance.

Sweet potato (cooked, plain)

Not a true potato and contains no solanine; rich in beta-carotene, which supports feather pigmentation and immune function in parrots and other psittacines. Offer steamed or baked without any additions.

Cooked butternut squash

Mild flavour most birds accept readily; provides vitamin A precursors and is low in oxalates. The flesh and seeds are both safe and offer a satisfying texture for larger parrots to forage.

Broccoli florets (raw or lightly steamed)

A nutritional powerhouse for birds, supplying calcium, vitamin C, and vitamin K. Small raw florets also provide excellent foraging enrichment for parrots, cockatiels, and conures.

Carrot (raw or cooked)

One of the most consistently safe vegetables across all companion bird species; high in beta-carotene with no toxic principles. Raw carrot sticks also serve as a beak-enrichment tool.

Cooked brown rice or quinoa

If the appeal of potato is its starchy, filling quality, plain cooked whole grains offer a comparable texture without any alkaloid risk and provide additional B vitamins and fibre.

Frequently asked questions

Can I give my parrot a small piece of baked potato skin?
Ideally, no — even from a potato with no visible green colouration, the skin retains a higher concentration of solanine than the inner flesh, and the margin of safety for a bird is narrow. If you want to share a bit of your baked potato, scrape out a small amount of the plain inner flesh only, ensure it has no butter, salt, or toppings, and keep the portion to a pea-sized amount for small birds or a teaspoon for larger parrots. The skin itself should always be discarded when feeding birds.
My budgie ate a tiny bit of raw potato. Should I be panicking?
A very small nibble of raw potato flesh — not green, not the skin — is unlikely to cause serious poisoning in most cases, but budgerigars are tiny and their threshold for solanine toxicity is genuinely low. Watch your bird closely for the next two to four hours for any signs of lethargy, fluffed feathers, regurgitation, or unusual droppings. If anything looks off, or if you are unsure whether any green or skin was involved, call an avian vet promptly rather than waiting. When in doubt with small birds, erring on the side of caution is always the right call.
Why is sweet potato considered safe for birds when regular potato is a caution food?
Despite sharing a common name, sweet potato (Ipomoea batatas) and the ordinary potato (Solanum tuberosum) are botanically unrelated — they come from entirely different plant families. Sweet potato belongs to the morning glory family (Convolvulaceae) and produces no solanine or related glycoalkaloids. This is why plain cooked sweet potato is widely recommended by avian vets as a nutritious treat, while regular potato demands much more careful preparation and carries a real risk if served incorrectly. The name overlap is genuinely misleading, and it is worth being explicit with any pet sitter or family member that these are very different foods from a safety perspective.
