Actually, the information on both links is incorrect (just because somebody wrote something on a birdsite, it doesn't mean is right or that the person who wrote it knows anything). The most common cause of birds regular dry sneezing is either lack of moisture in the air (not your problem as you are having a humid summer -this is usually a problem in the winter when we use dry heat in our homes) or lack of sufficient mucus in the respiratory passages. No mucus = no discharge - BUT no mucus also means fertile ground for infection as it's the mucus that cleans up the respiratory system of debris and bacteria. Lack of mucus is always caused by a diet that lacks sufficient betacarotene as it's vitamin A that allows the body to produce it. The problem with vit A is that the body was not created to ingest it in its final form (that of a vitamin) as it's not found in nature. What it is found is the precursor: betacarotene and, when the body ingests food with it, it processes it and changes it into vit A as long as there is enough fat for it (vit A is not water soluble so it needs fat to be absorbed by the body).
Parrots need a lot of betacarotene so feed foods rich in it on a daily basis: carrots, sweet potatoes, pumpkin, cantaloupe, papaya, dark leafy greens (dandelion grees are very high on it but even romaine lettuce is good), red/orange/yellow peppers, etc.
