Vomiting or Regurgitation in Pet Birds

Regurgitation, perhaps one of the most perplexing bird behaviors, occurs when a bird throws up small amounts of food with the intention of feeding it to a loved one. Regurgitation is perfectly normal behavior in birds, and not a reason for concern. Vomiting, however, is a sign of illness that should be addressed immediately.

Why Do Birds Regurgitate?

Regurgitation is a natural behavior related to bird parenting. In most cases, a regurgitating bird will bob its head and stretch out its neck during the process, and the food it produces will not be digested. In addition, a regurgitating bird will not show signs of illness or distress.

Regurgitation behavior in birds might best be observed in the nest. When a hen is sitting on eggs, the father of her chicks will many times gorge himself, only to return to the nest and purge to feed his mate. Once the eggs hatch, the resulting baby birds are completely dependent on their parents for food, requiring the adult birds to regurgitate their meals to feed their newborn offspring. It is a very efficient way of delivering food to their young. They needn’t carry anything and it has already been warmed up. because it is partially digested, it is a little easier for the babies to absorb the food delivered to them.

Regurgitation is also a way that birds show each other that they are “interested.” This is a natural courting behavior, and it’s very common for pet birds to regurgitate on other birds, their favorite people, or even their favorite toys. If your bird regurgitates on you, it’s most likely a sign of affection.

Signs That Your Bird Is Depressed

Not only are birds capable of becoming depressed, but prolonged depression can lead to self-destructive behaviors, lowered immune response, and an array of other problems. If you suspect that your bird may be depressed, compare its behavior with the points listed here. Signs pointing to depression may signal that you need to change something about your bird’s environment or your level of interaction with your pet.

Appetite Loss

Although it can be a symptom of several different types of issues in pet birds, one big indicator of depression is appetite loss. Because birds have such fast metabolisms, it’s important to learn to recognize them very quickly if your bird stops eating. Weight loss can come quickly and be very harmful to a bird, so if you notice that your pet’s food intake has changed for two consecutive days, you will want to schedule an appointment with your avian vet to investigate the matter.


One of the biggest and most easily recognizable signs that a bird is depressed is a sudden change in personality. Often, especially in parrots, this manifests itself as aggression. While aggression can be seasonal and related to hormonal issues, continually out-of-character behavior may be a sign that your bird is chronically unhappy. To be safe, have any sudden behavior changes investigated by a vet to rule out medical concerns. If your bird has a clean bill of physical health, then you should begin to assess what is going on in your bird’s life that could have triggered the behavior.

Feather Plucking

When a bird starts feather plucking, it can quickly progress into a chronic and devastating problem. If you start noticing bald patches on your bird, have your avian vet check things out so that you can rule out the disease. Once you are certain that there isn’t a medical issue in play, then you can try to figure out why your bird is plucking. Many birds start to pluck out of boredom or when they aren’t getting enough social interaction, so scheduling more time with your bird each day may be what your pet needs most of all.

Change in Vocalizations

You know your bird better than anybody—and if you have owned it for a while, then you should be pretty familiar with the frequency and types of vocalizations that your feathered friend makes on an average day. If you begin to notice a change in the level or kind of vocalizations that your bird is making, then it could be a sign that your pet is experiencing depression. Many birds resort to screaming out of boredom or frustration, so if your bird is louder than normal, it may be a sign that your pet would like to spend more time interacting with you.

Stress Bars

Another indicator that your bird could be stressed or depressed is the presence of stress bars on his or her feathers. While stress bars aren’t a health concern, they can clue you into problems with your bird’s overall happiness and quality of life. If you notice stress bars on your pet, take a good look at your bird’s diet, environment, play schedule, and interactions with you. If you see areas that could be improved, step things up a little bit and see if you can tell the difference in the way your bird looks and feels.

Why Do Birds Vomit?

While regurgitation is completely normal behavior, it is important to note that your bird may not be truly regurgitating every time it throws up. If it is vomiting rather than regurgitating, there is a good chance that it is ill or suffering from parasites.

It can be difficult to distinguish regurgitation from vomiting, but it’s important to do so. While true regurgitation is not stressful or violent in nature, a bird that is vomiting from illness will sometimes quickly flick its head, slinging the partially digested food all over. You may find digested food around the cage, or notice that your bird’s head feathers are stuck together or caked with food.

A vomiting bird will spew the contents of its stomach in a very messy and random manner. A bird that is regurgitating food brings it up from its crop and it is far more precise; in other words, its aim is better when it is regurgitating.

Vomiting can be the result of any of a number of physical problems including

  • Infections, including viral or parasitical infections, bacterial infections, or fungal infections; candida and tapeworm are particularly common issues
  • Diseases including heart, kidney, or liver disease, diabetes, or septicemia
  • Nutritional or dietary issues such as overfeeding, feeding too much protein or vitamin A, D, E, or iron
  • Food allergies
  • Change in diet
  • Poisoning as a result of accidental ingestion of certain foods, plant matter, pesticides, or household products
  • Gastrointestinal disease or blockage
  • Drug reactions
  • Physical or psychological stress as a result of a change in location or changes to the household structure (new pets, new people, etc.)


If you notice any sign that makes you think your bird could be vomiting from an illness, it is important to contact an avian vet immediately for an examination. Treatment may include:

  • Change of diet
  • Medications to treat an underlying disease or infection
  • Surgery for a blockage
  • Careful cleaning of the environment and removal of any potentially toxic substances

How to Prevent Vomiting in Birds

There is no way (or reason) to prevent regurgitation in birds, as it’s a natural behavior. Vomiting can’t be absolutely prevented, but these steps will reduce the likelihood of a health issue:

  • Provide your bird with an appropriate diet for its species, size, and age. If you are unsure about exactly which food is best for your pet, ask your vet.
  • Monitor your bird carefully when it’s out of the cage, making sure it doesn’t ingest stray items that could cause a blockage.
  • Carefully monitor your bird’s surroundings both in and outside the cage to be sure there are no potential choking hazards or toxic substances in the area.

In addition, keep a careful eye on your bird and check the cage when you’re cleaning it. If you notice signs of vomiting as opposed to regurgitation, take your bird to the vet as quickly as possible. While the problem may be benign, it may also be an early sign of a potentially serious problem.

WARNING: Be sure to identify these toxic foods so that you never serve them to your feathered friend

  • Chocolate
  • Garlic, onions
  • Castor beans, castor oil
