Squamous metaplasia of the glandular epithelium was found in the palatine salivary glands of two canaries, originating from a flock in which there was a variable intake of egg food. The histological changes, in combination with the history, indicate a vitamin A deficiency as a result of a selective intake of food as the most likely aetiology.
