Ingluvitis in Cockatiels: Inflamed Crop Causes and Care

Ingluvitis is inflammation of the crop (also called the ingluvies), a pouch in the lower neck where food is stored before it moves farther down the digestive tract. In cockatiels, an inflamed crop may become painful, swollen, slow to empty, or infected. Pet parents may also hear the term "sour crop," which is often used when food sits too long in the crop and begins to ferment.

In many birds, ingluvitis is not a stand-alone disease. It is often a sign of an underlying problem, such as yeast overgrowth, bacterial infection, irritation from something swallowed, poor hand-feeding technique in young birds, or a disorder that slows normal crop movement. Because cockatiels are small and can decline quickly, even mild-looking digestive signs deserve prompt attention.

The good news is that many cockatiels improve well when your vet identifies the cause early and matches treatment to the bird's condition, stress level, and your family's goals. The key is not to assume all regurgitation is behavioral. Repeated or messy regurgitation, weight loss, or a crop that stays full too long should be checked.

Several problems can inflame the crop in cockatiels. Yeast infection, especially Candida, is a well-known cause of crop disease in pet birds and may lead to regurgitation, crop distention, and delayed emptying. Bacterial infection can also affect the crop, particularly when normal crop movement slows and food sits too long. In some birds, the infection is primary. In others, it develops because another illness changed the crop environment.

Your vet may also look for protozoal disease, oral or upper digestive irritation, and foreign material or obstruction. Merck notes that cockatiels can be affected by regurgitation related to candidiasis, trichomoniasis, oral irritation, toxicosis, and crop or upper GI obstruction. Young birds are at additional risk if hand-feeding formula is overheated or feeding technique injures the crop.

Not every case starts in the crop itself. Viral disease, systemic illness, poor nutrition, stress, contaminated food or water, recent antibiotic use, and poor enclosure hygiene can all make crop problems more likely. That is why treatment often needs to address both the inflamed crop and the reason it happened.

Diagnosis starts with a careful history and physical exam. Your vet will want to know when the regurgitation started, what your cockatiel eats, whether the bird has lost weight, and if there were any recent changes in diet, environment, medications, or exposure to other birds. A crop that stays enlarged, painful, or slow to empty can be an important clue, but it does not tell the whole story.

In many cases, your vet will recommend crop cytology and sometimes culture. These tests help look for yeast, bacteria, inflammatory cells, and other abnormalities in crop contents. Depending on the signs, your vet may also suggest oral exam, fecal testing, bloodwork, and radiographs to check for obstruction, metal exposure, organ disease, or other causes of regurgitation.

If the case is severe, recurrent, or not responding as expected, more advanced diagnostics may be needed. These can include contrast imaging, endoscopy, or testing for underlying infectious or motility disorders. Because behavioral regurgitation can look similar at first, a veterinary exam is the safest way to sort out what is normal courtship behavior versus a medical problem.

Not every case can be prevented, but good daily care lowers risk. Keep food and water dishes clean, remove spoiled fresh foods promptly, and clean perches and enclosure surfaces regularly. Good hygiene matters because yeast and bacteria can take advantage of a stressed or unhealthy crop environment.

Diet and husbandry also play a role. Feed a balanced cockatiel diet, avoid sudden major food changes, and talk with your vet before using antibiotics or supplements. If your cockatiel is hand-fed or you care for chicks, formula temperature and feeding technique are especially important because overheated formula and feeding trauma can injure the crop.

Try to reduce chronic stress and watch for early changes in appetite, body weight, droppings, and behavior. A small gram scale is one of the most helpful home tools for bird families. Early weight loss can show up before obvious illness. Prompt veterinary care for regurgitation, slow crop emptying, or mouth lesions can prevent a mild crop problem from becoming a much bigger one.
