What is Respiratory Tract Infection?

Infections of the respiratory tract can develop from many other infections and conditions that cause problems in the chest, lungs, sinuses, and eyes of your bird. Viruses can severely compromise your bird’s immune system, while parasites and tumors can block breathing passages, cause swellings, and reduce lung function. While situations such as a nutritional deficiency or an allergy can be easily corrected, infectious agents can be more difficult to treat, and can be transmitted to other birds. These infections should be diagnosed as soon as possible for the safety of your avian population.

Wild, companion and poultry birds are all susceptible to a variety of respiratory infections. In some birds, symptoms can be mild, while in others, infections can become more severe, and lead to life threatening conditions. While you may think a bit of sneezing and wheezing may pass, these may be signs of a serious condition that needs to be treated to ensure the health of your bird.

Symptoms of Respiratory Tract Infection in Birds

The symptoms of a respiratory infection involve the eyes, sinuses, and respiratory tract. Due to the various types of causes that can result in such as infection, you are likely to see other symptoms in your bird that can help lead your veterinarian to a correct diagnosis. Be sure to note all symptoms that you see in your bird, however unrelated as they may seem, as many can be indicative of a certain disease or condition. Signs of respiratory distress include:

Causes of Respiratory Tract Infection in Birds

There are many causes of respiratory infections in birds. They include: 

  • Bacterial infections, such as Psittacosis, Infectious Coryza, Mycoplasma gallisepticum, Mycoplasma synoviae, or Mycoplasma meleagridis
  • Viral infections, such as Viscerotropic velogenic Newcastle disease, other paramyxoviruses, Avian influenza, Fowl Pox, Infectious Bronchitis, or Infectious Laryngotracheitis 
  • Fungal infections, such as Aspergillosis  
  • Parasitic infections, such as Syngamus trachea, Trichomoniasis, Sternostoma trachaecolum, Cryptosporidial, and Gapeworms
  • Allergies, such as from an allergen that is touch, inhaled, ingested, or even injected into your bird; birds can have seasonal allergies, or may be affected by lice or mites and asthma also occurs in birds
  • Nutritional deficiencies, specifically of Vitamin A and iodine
  • Cancer, such as tumors or masses within the chest or lungs

Diagnosis of Respiratory Tract Infection in Birds

Since there are such a wide variety of possible causes, your veterinarian will examine your bird, consider all the symptoms present, and perform tests to come to a correct diagnosis. Tests can include blood work, serum analysis, fecal samples, viral isolation tests like the agar gel immunodiffusion test, and the examination and PCR testing of biopsied trachea tissue and various bodily fluids. These tests can detect the presence of bacteria, viruses, parasites, and fungal infections. 

In birds, allergies can be diagnosed through blood tests that analyze white blood cell counts and skin biopsies, including feather follicles. A detailed history of exposure and a timeline of symptoms can help your veterinarian determine the actual allergen involved. Diagnosis is often confirmed by removal of the allergen from your bird’s environment that results in a resolution of symptoms. If your veterinarian suspects a mass or tumor is involved, imaging techniques such as X-rays, ultrasounds and CT scans can confirm it.

Treatment of Respiratory Tract Infection in Birds

Treatment will vary considerably, and will depend entirely on the diagnosis of the cause of your bird’s respiratory infection. Supportive care, dietary changes, and proper hygiene management are used in many cases to reduce the immunosuppressive effect of many conditions, and give your bird a better chance to recover. 

Vaccines are available for some viruses and bacterial infections, and may be able to prevent a fatality. Some viruses cannot be treated, however, so supportive care is given to make your bird more comfortable. Anthelmintic medications are administered for parasitic infections. Fungal infections are prescribed antifungal medications. For bacterial infections, antibiotics are often given, along with a flush of the nasal and sinus cavities. Vitamin A may also be given as a supplement for this type of infection, or to correct a nutritional deficiency.

Allergies can be treated by removing the allergen, administering antihistamines, and through the use of topical lotions when needed. Asthma can be treated with corticosteroids.

Any cancerous tumors can be treated in a variety of ways, from surgical removal to radiation and chemotherapy. Your veterinarian will discuss the best course of action for your bird’s condition.

Recovery of Respiratory Tract Infection in Birds

Your bird’s recovery from a respiratory infection is highly variable, and depends on the diagnosis made and the severity of your bird’s condition. While some causes can be easily treated, others, such as certain viruses, will be with your bird for life and may cause severe and life threatening complications. While vaccines are available for some infectious agents, they are more likely to help the other birds in the population by preventing them from becoming infected.

Noisy Breathing

My cockatiel is breathing heavy and hasn’t been active or eating or drinking. We consulted with a doctor who said she has a respiratory infection due to cold air from the AC. He prescribed baytril and vitamins for immune boosting. Wanted to know how long does it take for the bird to recover with this prescription because she isn’t eating at all

Hello I'm sorry to see that your pet is not feeling well. It can take up to two weeks for a respiratory infection to clear up. If she is not eating, she may have to be tube fed because it is not ideal for birds to go a long time without eating. Good luck and hope she feels better soon.

Hello, So sorry to hear about your bird. I would try to keep his nose clean as much as possible. Most birds do need antibiotics to clear this infection. Try to see if your vet can see you sooner than next week as birds can get very sick and die very quickly. Good Luck.

Thank you for your question. Unfortunately, without seeing your bird, I can't say whether he has an infection, an Allergy, or parasite. If the problem is not resolving, it would probably be best to have him seen by a veterinarian. They can examine him, see what might be going on, and get the best treatment for him. I hope that all goes well.

Thankfully Scarlet came back to you and you have her comfortable in her cage, during the past two days we don’t know what Scarlet has eaten or come into contact with; I would be cautious about heating her up too quickly as she will have difficulty regulating her body temperature. You should, to be on the safe side, visit an Avian Veterinarian for a once over to check for any other symptoms and to receive any antibiotics or other treatment if indicated.

Sneezing
Squeaking

My new budgie has been making this very random squeaking sound. I can't pin-point exactly why he's making the sound because I thought perhaps it was when he was moving or after he was running around - but he'll just be happy and playing and suddenly make a squeak or he'll squeak while he's sitting and looking around. It's just this small like squeak that's not accompanied by any labored breathing or tail bobbing but I'm worried it might be an upper respiratory infection as we got him from a pet store and I heard those are really common in birds from pet stores. I also believe he might've just sneezed which has me extra worried. Other than the possible sneeze and the random squeaks he's active, happy, curious, plays like no one's business - nothing is out of the ordinary except these two sounds.

Without examining Muffin I cannot say whether or not there is a cause to be concerned, sometimes budgies may have some difficulty adjusting to the air quality of a new environment or may have some respiratory infection. You should monitor Muffin for now, but visit a Veterinarian for a check to be on the safe side. Regards Dr Callum Turner DVM

I got two budgies just over a month ago. They are both under 6 months and I have noticed one of my budgies appears to be squeezing and sometimes let's out a squeak. The noises are mostly at night but are definitely becoming more common. Should I be concerned?

Breathing Difficulties,Quite Severe

Hello, My cockatiel was found at the bottom of an avory, a huge outside cage with many other birds flying about in it and he was born at the wrong time of year so no one knew he was there. He got kicked out or fell out and He had fully developed feathers by the time we found him except for the ones all the other birds had pulled out. He was running around the floor eating fallen seeds and his mother mustve been coming down and feeling him or he would have died of dehydration. He is a very happy bird but he's having difficulty breathing to the point he's always exhausted because of it. It sounds like theres ALOT of liquid in his lungs when you listen to the bubbly sound in his breathing. Sometimes if something's bothering him he will very very rarely give a extremely high pitched wheeze and that's about it. He doesnt fly due to his exhaustion although he can. He breathes with his mouth open quite wide 95% of the time. I wouldnt say hes suffering enough to be put down just yet although I wouldnt like this to get any worse. Please help me out. All this little bird wants to do is waddle to me with his broken toes that the birds had bitten and go to sleep. He always wants to be by me and it breaks my heart because he will even jump off the bed to get to me if I leave him on it. He will NOT leave my side and this poor little baby doesn't deserve to die so young. Please help me out, thank you. Extra info: He had red nostrils when we got him, dirt in them too but just a little. I fear birds faeces have fallen into his nostrils from being on the floor all the time. The only thing the medication has done for him was slightly get rid of the redness around his nostrils. He sneezes not that often but liquid does come out when he does and it doesnt smell that pretty. Also his age is... I don't know about 5 months but he's still very young but he can fly.
