My Mom has some sort of infgection eatrin her retinas & the Dr thikns it came from birds... Whether it was the paraskets she & her Mom/Aunts raiesd or the poutlry her family had when she was a kid is any one`s guess.
Don`t know if parrots duly carry the same bacterial fauna as the keets, but it is something to watch..To all intents and purposes .
