Enteritis in African Grey Parrots: Causes of Diarrhea, Weight Loss, and Digestive Upset
- Enteritis means inflammation of the intestines. In African Grey parrots, it can cause loose droppings, weight loss, poor appetite, fluffed feathers, and low energy.
- Diarrhea in parrots is not a diagnosis by itself. Infection, parasites, diet changes, toxins, stress, yeast overgrowth, and other digestive diseases can all look similar.
- See your vet promptly if your parrot has repeated watery droppings, is losing weight, stops eating, vomits, or seems weak. Birds can decline quickly from dehydration and underlying illness.
- A basic workup often includes an exam, weight check, droppings evaluation, Gram stain or fecal testing, and bloodwork. More complex cases may need cultures, PCR testing, or imaging.
What Is Enteritis in African Grey Parrots?
Enteritis is inflammation of the intestines. In African Grey parrots, that inflammation can interfere with normal digestion and absorption, leading to loose or watery droppings, weight loss, poor body condition, and digestive upset. Sometimes the problem is limited to the intestines. In other birds, enteritis is one part of a bigger illness involving the crop, liver, pancreas, immune system, or nervous system.
It is important to remember that not every wet dropping means true diarrhea. Birds normally pass feces, urates, and urine together, so droppings can look wetter when a parrot drinks more, eats juicy foods, or is stressed. True intestinal disease is more concerning when the fecal portion becomes unformed, the bird is losing weight, appetite drops, or other signs of illness appear.
African Greys can develop digestive signs from bacterial imbalance, yeast overgrowth, parasites, viral disease, toxins, and disorders such as avian bornavirus-related gastrointestinal disease. Because these causes overlap, your vet usually needs testing rather than appearance alone to sort out what is happening.
Symptoms of Enteritis in African Grey Parrots
- Loose, unformed, or watery feces
- Weight loss or prominent keel bone
- Reduced appetite or refusal to eat
- Lethargy, fluffed feathers, or sitting low on the perch
- Regurgitation or vomiting
- Seeds or undigested food in droppings
- Dehydration, tacky mouth tissues, or weakness
- Change in droppings color, including green feces or abnormal urates
See your vet immediately if your African Grey is weak, not eating, vomiting, passing very watery droppings, or losing weight. Birds often hide illness until they are quite sick. A kitchen gram scale can be very helpful at home. If your parrot is dropping weight over days to weeks, that is a strong reason to book an exam even if the droppings only look mildly abnormal.
What Causes Enteritis in African Grey Parrots?
Enteritis has many possible causes, and several can look alike at home. Common categories include bacterial overgrowth or infection, yeast problems such as Candida, intestinal parasites, diet-related irritation, sudden food changes, spoiled food, and exposure to contaminated water or droppings. Stress can also upset the digestive tract and may worsen disease that was already present.
Some parrots have digestive signs because of a broader medical problem rather than a simple intestinal infection. Merck notes that bacterial gastrointestinal infections can cause watery droppings and lethargy, and VCA lists infections, parasites, toxicities, nutritional imbalance, and organ disease among causes of anorexia and lethargy in birds. Merck also notes that avian bornavirus-related disease can affect African Grey parrots and may cause weight loss, vomiting, and seeds in the feces.
Other differentials your vet may consider include viral disease, heavy metal exposure such as lead or zinc, foreign material in the digestive tract, and secondary digestive changes from recent antibiotic use. In African Greys, chronic weight loss with digestive signs deserves a careful workup because the problem may be intestinal, but it may also involve the crop, proventriculus, liver, or whole-body health.
How Is Enteritis in African Grey Parrots Diagnosed?
Diagnosis starts with a hands-on exam and a very careful history. Your vet will want to know what your parrot eats, how long the droppings have been abnormal, whether there has been weight loss, any new birds or stressors in the home, and whether there was access to metal, plants, unsafe foods, or standing water. A current body weight is one of the most useful pieces of information in any sick bird.
Testing is chosen based on how stable the bird is and how long the problem has been going on. VCA describes common diagnostics for sick pet birds including blood chemistry, fecal examination for parasites, yeast, and bacteria, Gram stain of the stool, and cultures when needed. Merck notes that culture and cytology samples in birds may be collected from sites including the cloaca, blood, and internal organs depending on the case.
If signs are persistent, severe, or recurring, your vet may recommend a broader workup. That can include a complete blood count, chemistry panel, radiographs, crop or cloacal cytology, targeted PCR testing for infectious diseases, and sometimes imaging or endoscopy through an avian specialist. The goal is not only to confirm intestinal inflammation, but also to identify the underlying cause so treatment can be matched to the bird in front of you.

- Recheck visit to confirm droppings and weight are improving
Advanced / Critical Care
- Hospitalization for dehydration, weakness, or inability to eat
- Advanced bloodwork, radiographs, and infectious disease PCR testing
- Heavy metal testing, imaging, or endoscopy through an avian-focused practice when needed
- Intensive fluid therapy, assisted feeding, temperature support, and close monitoring

Questions to Ask Your Vet About Enteritis in African Grey Parrots
Bring these questions to your vet appointment to get the most out of your visit.
- Do these droppings look like true diarrhea, increased urine, or both?
- What is my parrot's exact weight today, and how should I monitor weight at home?
- Which tests are most useful first in my bird's case, and which can wait if we need a more conservative plan?
- Are you concerned about bacterial infection, yeast, parasites, toxin exposure, or a chronic digestive disorder?
- Does my parrot need bloodwork, radiographs, or infectious disease testing now?
- What supportive care should I provide at home for warmth, hydration, and feeding?
- What changes would mean I should come back urgently or go to an emergency avian hospital?
- When should we schedule a recheck to confirm the droppings and body weight are improving?
How to Prevent Enteritis in African Grey Parrots
Prevention starts with daily observation and good bird hygiene. Offer fresh food and clean water every day, wash bowls well, remove spoiled produce promptly, and keep perches and cage surfaces free of droppings buildup. Quarantine new birds and avoid sharing dishes or equipment between birds until your vet says it is safe.
Diet also matters. A balanced parrot diet helps support the digestive tract and overall immune health. Sudden food changes, high-fat seed-heavy feeding, and poor food storage can all contribute to digestive problems. If your African Grey needs a diet transition, make changes gradually and track droppings and weight during the process.
Routine wellness exams are one of the best prevention tools. Your vet can spot subtle weight loss, review droppings, and recommend testing before a mild problem becomes a crisis. For African Greys especially, regular gram-scale weights at home can catch chronic digestive disease early, often before a bird looks obviously sick.
