My Parrot Is Vomiting or Sick: What to Do Right Now

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-10-03

If your parrot is vomiting, the first thing to do is figure out whether it is true vomiting or normal regurgitation, because the two look similar but mean very different things. True vomiting in birds is an active, forceful, whole-body effort, and it is often a sign of serious illness. If you are asking "my parrot is vomiting what should I do," start by separating the two, then check for the emergency signs below.

Quick Answer

• Regurgitation is a controlled, head-bobbing motion where food comes up and is often re-swallowed or offered to you. It is usually behavioral and often normal.
• True vomiting is forceful, involves the whole body, and the bird cannot control it. Treat this as a medical problem.
• A parrot that is fluffed up, weak, not eating, or sitting on the cage floor is critically ill and needs a vet the same day.
• Do not try to force food, water, or human medicine into a vomiting bird. Keep it warm, quiet, and covered.
• Call an avian or exotic veterinarian right away. Birds hide illness until they are very sick, so waiting often makes things worse.

What Vomiting and Regurgitation Actually Look Like

Owners often use the word vomiting for both behaviors. In birds, they are different events.

Regurgitation is a voluntary action. Your parrot may bob its head, stretch its neck, and bring up a small amount of food or a mushy blob. It often re-swallows it or drops it in a tidy way. This is common in bonded birds, in birds feeding a mate or a toy, and in some birds during breeding season. The bird usually looks bright and normal before and after.

True vomiting is involuntary and forceful. The bird's whole body may lunge or pump, the head may shake side to side, and food or fluid may fly out or land on the feathers and face. Vomiting and retching are common signs of ill health in budgerigars, and the usual cause in that species is trichomoniasis of the esophagus, crop, or both [1]. A bird that vomits often looks dull, fluffed, or off balance afterward.

Watch for these clues that point to true vomiting:

• Food or mucus flung around the cage or stuck to the face
• Repeated episodes over hours or days
• The bird shakes its head or flicks its beak after bringing food up
• A wet or stained area on the chest feathers
• The bird seems tired, quiet, or unsteady afterward

A single regurgitation in an otherwise bright, eating, active bird is usually not an emergency. Repeated forceful vomiting is.

Main Causes of Vomiting in Parrots

Many conditions can cause a parrot to vomit. Some are mild and some are life threatening. The table below lists common causes and how urgent each one tends to be.

Some of these problems overlap. A bird with proventricular dilatation syndrome may vomit for weeks before an owner realizes something is wrong [3]. A bird with Pacheco's disease may go downhill fast, and the infection can spread to other birds in the home [2]. Cryptosporidium can cause vomiting along with diarrhea and poor feather condition, and it is found in parrots [4].

If you also keep dogs or cats, the same "is this serious" question comes up with them. The logic is similar: forceful, repeated vomiting with a sick pet is a vet problem.

Red Flags That Mean an Emergency

Call an avian or exotic veterinarian immediately, or go to an emergency clinic that sees birds, if you see any of these:

• Forceful vomiting that keeps happening
• Blood in the vomit or droppings
• The bird cannot stand or is falling over
• Seizures, head tilt, or twisting of the neck
• Labored breathing, tail bobbing, or open-mouth breathing
• The bird is fluffed up and sitting on the cage floor
• No eating or drinking for more than a few hours
• A swollen or sour-smelling crop
• Sudden weight loss or a sharp breastbone
• Known or suspected contact with a toxin, such as lead or zinc
• Other birds in the home are also sick

A bird that is weak, not eating, vomiting, and has loose droppings may have a serious systemic disease such as Pacheco's disease, which can be fatal [2]. Do not wait to see if it passes.

What You Can Safely Do at Home While You Wait

You cannot treat vomiting in a parrot at home. What you can do is keep the bird stable and safe until you reach a vet.

• Move the bird to a quiet, warm, dim area away from other pets and loud noise.
• Keep the cage covered on three sides to reduce stress.
• Offer a shallow dish of fresh water, but do not force the bird to drink.
• Remove food that spoils quickly. Leave a small amount of the bird's normal food if it wants to eat.
• Do not give human medications, including anti-nausea drugs. A drug that helps one species can harm a bird. In one reported case, a macaw with chronic vomiting was given metoclopramide and developed severe neurologic signs, then died despite supportive care [5]. Dosing for birds must be calculated by a veterinarian from the bird's weight and health.
• Do not try to flush the crop or give home remedies.
• Note the time, what came up, and how often. Take photos or a short video. This helps your vet.
• If you suspect a toxin, call your veterinarian or a pet poison hotline right away.

If you have a dog or cat that is also vomiting, some of the same home-care rules apply. For example, Dog Vomiting Yellow Bile What To Do covers what to do when a dog brings up bile and will not eat.

What Your Veterinarian Will Check and Test

Your vet will start with a full history and a physical exam. They will ask about diet, recent changes, other birds in the home, and how long the vomiting has lasted.

Expect some of these steps:

• Weigh the bird and check its body condition
• Feel the crop and abdomen for swelling, thickening, or a mass
• Look inside the mouth and throat
• Check for dehydration and neurologic signs
• Examine the droppings

Common tests include:

• Fecal testing for parasites such as Trichomonas and Cryptosporidium [1][4]
• Crop swab or crop wash to look for infection
• Blood work to check organ function and infection
• Imaging such as radiographs or contrast studies to look at the proventriculus and intestines [3]
• Testing for specific viral diseases if the history suggests it [2]

Treatment depends on the cause. A bird with trichomoniasis needs specific antiprotozoal medication [1]. A bird with proventricular dilatation syndrome needs supportive care and a careful diet plan. A bird with a severe viral disease may need isolation and intensive care [2]. Your vet will decide what is safe for your bird.

Prevention and Daily Monitoring

You can lower the risk of vomiting and catch problems earlier with a few habits.

• Weigh your bird weekly on a small kitchen scale. A drop in weight is often the first sign of illness.
• Watch droppings daily. Changes in color, consistency, or number matter.
• Keep the cage clean and remove spoiled food quickly.
• Quarantine any new bird for at least 14 days before mixing it with your flock. Strict quarantine and disinfection helped limit one outbreak of a fatal viral disease in an aviary [2].
• Avoid giving birds access to metal objects, old paint, or toys with exposed lead or zinc.
• Keep the diet balanced. Seed-only diets can lead to health problems over time.
• Schedule a yearly exam with an avian vet, even if your bird looks fine.

If your bird has a chronic condition such as proventricular dilatation syndrome, your vet may want regular checkups and weight logs [3]. Keep a simple notebook or phone note with dates, weights, and any vomiting episodes.

Limitations and When to Contact a Veterinarian

This article cannot tell you what is wrong with your specific bird. Only a veterinarian who examines your parrot can do that.

Contact a veterinarian the same day if your bird:

• Vomits more than once
• Looks fluffed or tired
• Eats less than usual
• Has changed droppings

Go to an emergency clinic now if your bird:

• Cannot stand or is having seizures
• Is breathing hard or open-mouth breathing
• Has blood in the vomit or droppings
• Has a swollen crop or a sour smell
• Is known to have eaten something toxic

A routine visit is fine for mild, one-time regurgitation in a bright, eating, active bird, but mention it at the next checkup. When in doubt, call. Birds often hide illness until they are very sick, and early treatment gives the best chance.

Frequently Asked Questions

How do I tell regurgitation from vomiting in my parrot?

Regurgitation is a controlled head-bobbing motion where food comes up and is often re-swallowed or offered to a mate. Vomiting is forceful and involves the whole body, and the bird cannot control it. If food flies out or the bird looks sick afterward, treat it as vomiting.

My parrot vomited once and seems fine. Do I need a vet?

A single episode in a bright, eating, active bird is often not an emergency. Watch closely for the next 24 hours for more vomiting, fluffed feathers, or changes in droppings. If anything changes, call your vet.

Can I give my parrot human anti-nausea medicine?

No. Never give human medicine to a bird without veterinary direction. One macaw with chronic vomiting developed severe neurologic signs after receiving a drug called metoclopramide and later died [5]. Your vet will calculate any dose from your bird's weight and health.

What diseases cause vomiting in parrots?

Causes include trichomoniasis, Pacheco's disease, proventricular dilatation syndrome, and Cryptosporidium infection [1][2][3][4]. Crop infections, toxins, and stress can also cause it. Your vet will test to find the cause.

Should I isolate my vomiting parrot from my other birds?

Yes, isolate the sick bird in a separate room and wash your hands and change clothes before handling other birds. Some causes of vomiting, such as Pacheco's disease, can spread through a flock [2]. Call your vet for guidance on quarantine and testing.
