Canary Eye Infection

Symptoms of eye infections

  • Infected birds may have red, swollen, runny or crusty eyes. In severe cases, the eyes become swollen shut and the bird becomes blind and unable to fend for itself
  • Birds with conjunctivitis may also suffer from associated respiratory problems, which can result in death


These would be the possible reasons for your canary to develop an eye infection:

  • Bacterial or viral infection

       1.   Conjunctivitis is a common eye disorder, which is usually caused by bacteria and can be identified as red and swollen eyelids. Conjunctivitis is also a symptom of many other medical problems, including respiratory infections.

       2.   Mycoplasma infection also causes conjunctivitis with the symptoms of swollen eyelids, ocular and nasal discharge, impaired vision, depression, and weight loss. Once birds have been infected, they become carriers and remain infectious for life. Infected Canaries can transmit the disease through their eggs to the chicks, further perpetuating the disease.

       3.   Fungal Infection of the eye can also lead to bird eye disorder. One common fungus, Aspergillus, infects the bird’s respiratory system, but can also affect brain and eyes. The infected eye will show yellow plaques under the eyelid. The eye will also have inflammation, and if left untreated, this infection can result in severe eye damage

  • Vitamin A and E deficiency

Vitamin deficiency is another cause of eye disorders in birds. For instance, a deficiency in vitamin E in the parent can lead to the birth of a blind chick, and vitamin A is required for proper pigmentation and tearing of the eyes.

  • Dirty cages/perches
  • Eye injuries


  • Contact between susceptible birds or infected surfaces (like feeders) .An unproven theory is that birds can be infected by contact with asymptomatic carriers (birds carrying Mycoplasma, but not showing symptoms).


Treatment of eye infection

  • The first step involves isolating the canary from other birds
  • In case of a simple eye infection, treat the bird with an antibiotic ointment like Polysporin eye drops, or apply antibiotic eye drops such as Terramycin, Tobramycin or TriOptic-S. This treatment may resolve the problem without using oral antibiotic treatments
  • If the cause is a sinus problem oral antibiotics may be prescribed in addition to eye ointments. Many cases have responded well to Tylosin. Tylan and Baytril are frequently prescribed, but some other antibiotics may work just as well.
  • If it is Mycoplasma treat the birds with Tylosine or Doxycicline antibiotics
  • Colloidal silver is also used as a natural remedy for eye infection
  • Add Vitamin A supplements in the recovery process
  • Contact a Veterinarian before using an antibiotic treatment to the Canaries and follow Vet’s instructions on how to use them


  • Quarantine new birds for at least two weeks. If you see eye problems in any of your birds, remove the bird from the flock and watch carefully for respiratory problems.
  • To prevent your canary from developing an eye infection, maintain a clean bird cage and disinfect the cages and perches
  • Provide a rich diet of Vitamin supplements to birds
  • Added garlic and Apple Cider Vinegar in water, which are great for building the immune system


I hope this information will help controlling eye infection for your Canaries.
