Avian Diarrhea

Avian diarrhea is a common issue with birds, and it can have several different causes. Avian diarrhea can be caused by viruses, bacteria, fungi, parasites, and toxins. Noninfectious causes can include changes in their diet, stress, environmental factors like temperature extremes, or internal organ dysfunction. Nutritional deficiencies or imbalances can also lead to avian diarrhea.

Smaller birds like Lovebirds, Finches, Parakeets, Cockatiels and Parrotlets are more likely to have diarrhea than larger birds. Diarrhea is also much more common with birds that have compromised immune systems.

Symptoms of Avian Diarrhea

The most obvious symptom of diarrhea is frequent and watery droppings. Other symptoms can include:

  • Appetite loss
  • Lethargy
  • Weight loss
  • Dehydration
  • Signs of pain

Depending on the cause, other symptoms like vomiting or regurgitation could be present as well. If you observe any of these symptoms in your bird, it’s important to get seen by your veterinarian.

Diagnosing Avian Diarrhea

In order to accurately diagnose diarrhea, it’s important to take your bird to a veterinarian. Your vet will perform a complete physical exam and might collect samples of your bird’s droppings for further examination in the lab. Your vet can also recommend additional diagnostic tests such as blood work, imaging studies (x-rays or ultrasound), or endoscopy to further investigate the cause of their diarrhea.

Stages of Avian Diarrhea

Avian diarrhea can be split into three types: acute, subacute, and chronic.

Acute

Acute diarrhea is the most severe and is usually caused by a virus or a bacterial infection. Symptoms can appear suddenly and include frequent, watery droppings, appetite loss, lethargy, weight loss, dehydration, and signs of pain. Your bird might need to be hospitalized for supportive care and antibiotic treatment.

Subacute

Subacute diarrhea is less severe than acute, but could still need veterinary attention. Causes can include dietary changes, stress, or environmental factors. Symptoms might be milder and can include occasional loose droppings, appetite loss, or lethargy. Treatment will depend on the cause and can include diet modification or antibiotics if an infection is present.

Chronic

Chronic diarrhea is the mildest form and usually occurs when there is an underlying health issue like nutritional deficiencies or organ dysfunction. Symptoms can include occasional loose droppings, appetite loss, or lethargy. Treatment will depend on the cause and could include dietary modification or antibiotics if an infection is present.

Avian diarrhea can be a serious problem, so it’s important to take your bird to the vet if you notice any of the above symptoms. Your vet will be able to determine the cause and give them the appropriate treatment.

Treating Avian Diarrhea

Treatment of avian diarrhea depends on the underlying cause. Treatment can include dietary modification, antibiotics, anti-parasitic medication, or supportive care such as fluids and electrolytes. It’s important to follow your vet’s instructions carefully and to give any prescribed medications as instructed. If the underlying cause is not determined or can’t be treated, then supportive care may be recommended to help them recover.

Preventing Avian Diarrhea

The best way to prevent avian diarrhea is to feed your birds a healthy diet, give them a stress-free environment, and regular veterinary check-ups. Good hygiene practices (such as washing your hands and disinfecting surfaces) can also help reduce the spread of infectious agents.

Avian diarrhea can have serious consequences if not treated promptly, so it’s important to take your bird to the vet if you notice any of the symptoms described above.
