"Birds see in colour which is important in recognising food and danger and is possibly used in mating rituals. Birds also see with enormous accuracy and at long distances. Some have very advanced depth perception and motion detection capabilities.."(reference:THE MARVELOUS AVIAN EYE by Linda Pesek DVM"
Inflammation and infection of the eyelids and conjunctiva in birds have been related to various organisms. Vitamin A deficiency can also present with eye problems. Vitamin A should be supplemented when treating any suspected poxvirus infections.
Various viruses can also cause problems.
Various bacterial can cause conjunctivitis and swelling in the sinuses.
All this aside, Eye problems are rare in Canaries and in 30 Years I have only seen 1 Canary born blind.
It is also suggested that Cinnamon birds because of their Pink Eyes are more susceptible to Cataracts, although I have never seen evidence of this.
The symptoms of eye problems can be:
Where a bird has an infection or injury.
Where a bird is blind it will have difficulty feeding itself and will be unable to fly successfully, however in a small cage it will survive on the floor.
