Parrot Vomiting Associated With Breathing: Causes & Vet Care
Vomiting associated with breathing in parrots can have several causes. Learn what to observe, what may be behind it, and when to seek avian veterinary care.
Quick Answer
Vomiting in parrots involves forceful, whole-body effort with head flicking and is different from regurgitation, which is a gentler, often normal courtship behavior. Vomiting may indicate infection, toxin ingestion, crop disease, or digestive obstruction. Repeated vomiting, blood in the material, lethargy, or a fluffed parrot not eating requires prompt evaluation by an avian veterinarian. When this sign occurs or worsens associated with breathing, environmental factors, overnight changes, or timing-related patterns may provide additional clues. Persistent or worsening signs should be evaluated by an avian veterinarian.

What vomiting can look like in parrots
Parrots are prey animals and naturally hide signs of illness, so observable changes are important to take seriously. Vomiting in a parrot may appear as:
- Forceful expulsion of food or fluid with a head-flicking motion
- Vomited material on the cage walls, perches, or head feathers
- Sour or foul smell from the mouth or cage
- Fluffed feathers, lethargy, or sitting on the cage floor
- Refusal to eat or drink
- Swollen or firm crop that does not empty
- The sign is noticed or worsens particularly associated with breathing
What may be associated with vomiting
Several factors may contribute to vomiting in parrots. Similar signs can have different underlying causes, so a veterinarian's assessment is important.
Crop infection (sour crop). Overgrowth of yeast (most commonly Candida) or bacteria in the crop can cause food to ferment rather than move through, leading to vomiting. The crop may feel squishy or smell sour. This is more common in young birds but can affect adults.
Bacterial or viral gastrointestinal infection. Infections of the digestive tract can cause vomiting along with changed droppings, lethargy, and appetite loss. PDD (proventricular dilatation disease) is a viral condition that affects the nerves of the digestive tract and can produce chronic vomiting and weight loss.
Toxin ingestion. Ingestion of toxic plants, household chemicals, heavy metals such as lead or zinc, or unsafe foods can cause vomiting. Parrots are curious and may chew on items that are dangerous.
Foreign body obstruction. A parrot that swallows a non-food object, such as a toy part or large seed, may develop a blockage in the crop or proventriculus, causing vomiting and distress.
Dietary indiscretion. Eating spoiled food, too much rich or fatty food, or a sudden diet change can irritate the digestive tract and cause vomiting in some parrots.
Respiratory system involvement. When a sign is directly linked to the breathing process, it often points to the respiratory tract, air sacs, or sinuses. Parrots have a unique respiratory system with air sacs that makes them particularly vulnerable to airborne irritants and infections.
Airborne toxin sensitivity. Parrots are exceptionally sensitive to fumes from overheated non-stick (PTFE) cookware, aerosol sprays, and smoke. Any sign linked to breathing that follows possible fume exposure is an emergency.
What to monitor at home
If your parrot is showing this sign, the following details can help you and your veterinarian assess the situation:
- Frequency: how many vomiting episodes occur and over what period
- Appearance: whether the material contains food, fluid, blood, or looks fermented
- Crop: whether the crop feels full, firm, or squishy and whether it empties between episodes
- Behavior: alertness, appetite, thirst, and activity level
- Droppings: color, consistency, and frequency
- Recent diet changes, new foods, or access to non-food items
- Whether the sign occurs with every breath, during inhalation or exhalation, and whether breathing sounds such as wheezing or clicking are present
What you can safely do next
Remove food temporarily and offer small amounts of water to prevent dehydration, but do not force-feed. Keep the parrot warm and calm. Never attempt to induce vomiting in a parrot, as this can be dangerous. Contact an avian veterinarian promptly, especially if vomiting is repeated or the bird appears fluffed and lethargic. Remove the parrot from any environment with fumes, smoke, or aerosols and ensure good ventilation.
When to Contact a Veterinarian
Parrots require care from veterinarians who specialize in avian medicine, as not all veterinarians treat birds. If you observe any of the following, contact an avian veterinarian or an avian emergency clinic immediately:
- Repeated or continuous vomiting
- Blood in the vomited material or material that looks like coffee grounds
- A swollen, firm, or doughy crop that does not empty
- Fluffed feathers, lethargy, not eating, or sitting on the cage floor
- Vomiting after known or suspected ingestion of a toxic substance or foreign object
- Signs of dehydration: sunken eyes, weakness, or no droppings
Even without emergency signs, it is advisable to contact an avian veterinarian if the sign persists for more than a day, worsens, or is accompanied by reduced appetite, changed droppings, or reduced activity. Young birds, small species, and parrots with existing health conditions can deteriorate more quickly and may need earlier evaluation.
An avian veterinarian can perform a physical examination, listen to the air sacs and heart, and recommend diagnostic tests such as blood work, radiographs, or crop and choanal swabs to help identify the underlying cause and guide treatment.
Frequently Asked Questions
How can I tell vomiting from regurgitation in a parrot?
Regurgitation is a gentle, rhythmic bobbing motion that brings up undigested food, often as a courtship or bonding behavior directed at a person, toy, or mirror. Vomiting is forceful, involves whole-body effort and head flicking, and scatters material around the cage. Vomiting is almost always abnormal and warrants veterinary assessment.
Can I give my parrot anything to stop vomiting?
No. Do not give human anti-nausea medications, home remedies, or any over-the-counter product to a vomiting parrot. Treatment depends on the underlying cause, which an avian veterinarian must identify. Supportive care such as warmth and fluids should be guided by professional advice.
Is it an emergency if my parrot vomits once?
A single episode of vomiting in an otherwise bright, eating parrot may not be an emergency, but it should be monitored closely. Repeated vomiting, blood, a swollen crop, lethargy, or not eating are emergency signs that require immediate avian veterinary care.
