Parrot Diarrhoea: Causes and When to Call an Avian Vet

A watery-looking dropping can be worrying, especially when your parrot has seemed well until now. Parrot diarrhoea is not always what it first appears to be, but a repeated change in droppings should never be ignored.

Parrots often hide illness until they are feeling quite unwell. A calm check of the cage liner, your bird’s appetite and their usual behaviour can help you decide whether to monitor closely or contact an avian vet straight away.

Key Takeaways

• True diarrhoea means the faecal part of the dropping has lost its shape. Extra clear liquid around a formed dropping is usually increased urine, known as polyuria.
• Fresh, watery foods can cause temporary polyuria, but they should not cause repeated unformed faeces.
• Diet changes, stress, infections, toxins and internal illness can all cause parrot diarrhoea.
• Contact an avian vet promptly if diarrhoea continues for more than 24 hours, or sooner if your parrot seems unwell.
• Blood, black droppings, weakness, vomiting, breathing changes, loss of balance and an inability to perch need urgent veterinary advice.

Is It Diarrhoea or Polyuria?

A normal dropping has three parts. There is the formed faecal section, which is often green or brown, the white or cream urates, and a small amount of clear urine.

The amount, colour and shape can change slightly with diet, species and time of day. What matters most is knowing what is normal for your individual parrot.

What true diarrhoea looks like

With true diarrhoea, the faecal section becomes soft, shapeless, smeared or fully liquid. It may be hard to see a separate formed part at all.

This is different from a normal-looking green or brown faecal portion sitting in a larger puddle of clear fluid. VCA’s guide to abnormal bird droppings explains this important difference between diarrhoea and polyuria.

One unusual dropping is not always an emergency. A repeated pattern over several cage changes gives a much clearer picture.

When extra urine has a simple cause

Cucumber, melon, leafy vegetables and other moist foods can increase the clear urine around an otherwise formed dropping. A large first-morning dropping can also look looser, particularly if your parrot has held it overnight.

Lorikeets and other nectar-feeding species naturally produce wetter droppings than many seed or pellet-eating parrots. Keep this in mind before assuming there is a health problem.

Make a note when you offer new food or treats. If the droppings settle once that food has passed through, and your parrot remains bright, eating and comfortable, it may simply have been a short-term change.

Common Causes of Parrot Diarrhoea

Parrot diarrhoea can follow something as simple as a sudden food change. It can also be an early sign of a condition that needs treatment. Droppings alone cannot identify the cause, so your vet will consider the whole picture.

Diet changes, stress and digestive upset

Too much fruit, a sudden switch from seed to pellets, spoiled food and unfamiliar treats can upset a parrot’s digestive system. A change in household routine, travel, boarding, a new bird nearby or a frightening event may also affect droppings for a short time.

Keep food changes gradual where possible. A parrot that is already unwell should not have their usual diet changed suddenly unless a vet advises it.

Poor nutrition can affect several areas of health, not only droppings. Our guidance on vitamin A deficiency symptoms in parrots also covers dietary warning signs that deserve veterinary attention.

Infection, toxins and internal illness

Bacterial, fungal and parasitic infections can cause loose faeces. Chlamydiosis, liver disease, kidney disease, diabetes and heavy-metal toxicity from lead or zinc are also possible causes.

Some digestive disorders may bring other signs, including weight loss, regurgitation, weakness or undigested food in the droppings. The MSD Veterinary Manual’s overview of digestive disorders explains why these signs need proper assessment.

Dirty water bowls, mouldy food, rodent contamination and poor cage hygiene can create avoidable risks. The Parrot Society UK’s advice on contamination risks is a useful reminder to keep food, water and living areas clean and dry.

A loose dropping is a sign, not a diagnosis. Treating at home with leftover medicines can hide the problem and make your parrot harder to assess.

Safe Steps to Take at Home

You do not need to solve the cause before calling a vet. Your job is to keep your parrot safe, warm and settled while you gather useful information.

Keep the environment calm and familiar

Place your bird in a quiet, draught-free room, away from other pets, smoke, scented products and household activity. Keep their normal food and fresh water available unless the vet gives different instructions.

Use plain paper beneath the cage grate so you can see each dropping clearly. Avoid scented liners, glossy paper and loose bedding that can hide the shape and amount of the droppings.

If your parrot is weak, lower the perches or provide a safe, padded floor area. A bird who is struggling to balance should not have to climb.

Monitor without over-handling

Check whether your parrot is eating, drinking, perching and responding normally. Take clear photographs of the droppings and write down when the change began.

A small digital gram scale is one of the kindest tools a parrot owner can keep. Regular weighing can show weight loss before it is obvious by eye.

Do not give human medicines, leftover antibiotics, anti-diarrhoea products, herbal remedies or high-dose vitamins. Do not force-feed or force water a parrot who is vomiting, weak or having difficulty swallowing, as food or liquid can enter the airway. Trouble moving food through the crop is another emergency, and our guide to parrot crop stasis explains when to seek urgent vet care.

When Parrot Diarrhoea Needs an Avian Vet

A healthy parrot should not have ongoing watery, unformed faeces. It is always better to call early and let the clinic guide you than to wait until your bird is visibly distressed.

Use the 24-hour rule

If true diarrhoea lasts longer than 24 hours, contact an avian vet as soon as possible. Call sooner if there is no clear food-related explanation, or if the droppings worsen over a few hours.

A parrot can appear alert while losing fluids, eating less or developing a more serious illness. Changes in appetite, posture, activity and dropping volume all matter alongside the appearance of the faeces.

The BSAVA’s information on abnormal or loose droppings notes that abnormal droppings and reduced appetite are common early signs of digestive disease in birds.

Signs that need urgent help

Contact an avian vet or emergency practice without waiting if you see any of the following:

• Blood, black tar-like material or a sudden unexplained red colour in the droppings.
• Green or yellow urates, an unusually strong smell, or undigested food.
• Very few droppings, or urine and urates with no visible faecal section.
• Fluffed feathers, unusual sleepiness, weakness, collapse or sitting on the cage floor.
• Repeated vomiting, refusal to eat, marked weight loss or a swollen abdomen.
• Open-mouth breathing, tail bobbing, tremors, seizures, loss of balance or an inability to perch.

Call ahead before travelling, particularly outside normal hours. Tell the clinic that you have a parrot and describe the signs clearly, so they can advise where to go.

Help Your Vet Find the Cause

An avian vet may assess your parrot’s weight, hydration, crop, abdomen and general condition. They may also recommend faecal testing, blood tests, swabs, X-rays or other checks based on the signs and history.

Bring photographs of recent droppings if you have them. If the clinic asks for a sample, use a clean sealed container or bag, but never delay the journey to collect one.

Write down your parrot’s species, age, usual diet, recent food changes, supplements, medication and any possible exposure to metal, plants, chemicals or fumes. Mention travel, new birds, boarding, household changes and whether anyone else in the home has noticed a change.

If illness has become part of a wider care difficulty, asking for help is a responsible decision. Our parrot surrender and rescue support offers a safe and non-judgemental route for owners who can no longer meet their bird’s needs.

Rescue parrots often arrive needing assessment, treatment, careful nutrition and time to settle. You can Help a Parrot in Need – Support Rescue, Healing & Safe Rehoming so vulnerable birds can receive the care and safe future they deserve.

Frequently Asked Questions

Can stress cause diarrhoea in parrots?

Stress can affect a parrot’s droppings, particularly after travel, a frightening event, a new environment or a major routine change. It is still important not to assume stress is the only cause.

If the faecal part remains unformed, your parrot is quieter than usual, or the change continues, speak to an avian vet. Stress and illness can happen at the same time.

Should I stop feeding a parrot with diarrhoea?

Do not withhold your parrot’s normal food without veterinary advice. Sudden dietary changes can create further problems, and sick birds need support to maintain their energy.

Offer familiar food and fresh water, keep the environment calm and contact your vet. If your bird is vomiting, cannot swallow or is very weak, do not force food or water.

Can I give my parrot medicine for diarrhoea?

No. Human medicines and leftover bird treatments can be dangerous, even in small amounts. The wrong medication may harm the liver, affect the gut or delay the right diagnosis.

Your vet can decide whether tests and treatment are needed. Until then, careful observation and a clean, calm setup are safer than home remedies.

A Change Worth Taking Seriously

Your parrot’s droppings are one of the clearest daily signs of their health. A formed faecal section with extra urine may be temporary, but repeated unformed faeces need attention.

Knowing your bird’s normal routine helps you spot the small changes that matter. Prompt veterinary advice gives your parrot the best chance of safe, appropriate care.
