Why Is My Cockatiel Regurgitating? Affection, Hormones, or a Medical Problem

Behavioral regurgitation is usually a deliberate social display. Your cockatiel may bob the head, stretch the neck, and gently bring up partially softened food toward a favorite person, mirror, bell, perch, or another bird. Many parrots do this during courtship because offering food is part of mate bonding.

These episodes are often brief, and your bird otherwise acts normal. Appetite, energy, droppings, and breathing stay the same. The behavior may increase in spring, after longer light exposure, or when your cockatiel spends a lot of time with mirrors, nest-like spaces, or intense petting along the back and under the wings.

Hormones can make regurgitation more frequent and more focused. Cockatiels may become territorial, vocal, nest-seeking, or fixated on one person or object. They may also masturbate on toys or perches, crouch with wings slightly lifted, or become frustrated when separated from the chosen bond target.

You can often reduce hormonally driven regurgitation by limiting daylight to a more appropriate schedule, removing mirrors and nesting triggers, rotating toys, avoiding petting that mimics mating behavior, and encouraging foraging and exercise. These steps do not replace veterinary care, but they can help lower the intensity of the behavior.

Medical regurgitation tends to look less purposeful. Food or fluid may come up repeatedly without a social trigger, and your cockatiel may seem nauseated, weak, fluffed, or unwilling to eat. Some birds show repeated swallowing, crop discomfort, bad breath, weight loss, diarrhea, mouth plaques, or mucus.

Merck notes that regurgitation in pet birds has a broad differential list, including behavioral courtship, crop and mouth disease, and infections such as trichomoniasis. In cockatiels, white material in the mouth, mucus, or crop irritation should raise concern. Because birds hide illness well, even subtle changes deserve attention.

Pet parents often use these words interchangeably, but they are not the same. Regurgitation is usually a passive or semi-purposeful bringing up of food from the crop or esophagus. Vomiting is more forceful and can spray material, often with head flicking and a distressed appearance.

If your cockatiel is flinging food, has material on the head, seems weak, or is bringing up liquid repeatedly, treat that as more urgent. See your vet promptly, because vomiting in birds is more likely to signal illness than normal courtship behavior.

See your vet soon if the regurgitation is new, frequent, worsening, or not clearly tied to courtship. Also book an appointment if your cockatiel has weight loss, appetite changes, droppings changes, lethargy, breathing changes, mouth lesions, or a swollen crop. A video of the episode, recent diet details, and a gram weight trend can help your vet sort out behavior from disease.

If your bird is weak, sitting puffed up, struggling to breathe, unable to keep food down, or has possible toxin exposure, do not wait. Birds can decline quickly, and early care often gives your vet more treatment options.

Your vet will usually start with a physical exam, weight check, and a close look at the mouth and crop. Depending on the history and exam findings, they may suggest crop cytology, fecal testing, bloodwork, radiographs, or targeted infectious disease testing. In some cases, treatment focuses on husbandry and hormone control. In others, your vet may recommend medications or supportive care for crop disease, infection, inflammation, or dehydration.

Typical 2025-2026 U.S. avian cost ranges vary by region, but many pet parents can expect about $85-$220 for an avian exam, around $25-$50 for basic fecal or cytology testing through a diagnostic lab, roughly $46-$90 for an avian CBC or hemogram, and about $150-$400 or more for urgent visits or imaging. Your actual cost range depends on location, urgency, and whether your cockatiel needs same-day supportive care.
