Parajita,
I have to say that I deeply respect your dedication to your parrots. I know that by this point you are tired and wish you wouldn't have chosen this path but I am sure you have some brilliant and helpful information you can share with people. You should consider writing a book or posting a blog if you haven't already.
I hope you don't mind if I pick your brain from time to time.
How do I know what plants and foods contain salicylates? I'm looking it up now, I came across willow bark, but nothing else specific. Says it is used in NSAIDs also. Scary stuff it sounds like!
Thank you again for taking the time to inform me of the importants of my decision and the tips you have given me so far.
UPDATE!!
This is what I found so far...
Unripe fruits and vegetables are natural sources of salicylic acid, particularly blackberries, blueberries, cantaloupes, dates, grapes, kiwi fruits, guavas, apricots, green pepper, olives, tomatoes, radish and chicory; also mushrooms.
