This is an interesting thread and lead to the pursuance of facts and information regarding allergic alveolitis.
Interestingly enough, it is not only seen in humans, but New World Parrots, as Dave has stated. One thing to note on this Allergy, is some humans and some parrots are thought to be possibly genetically predisposed to it and others will never experience an allergic reaction to Dander. However, any human or parrot that does in fact have allergic alveolitis, will also be hyper-sensitive to and suffer from mold spores, bird droppings Etc.
This allergy decreases lung capacity and causes impaired diffusion of air through the alveoli of the lungs.
So the answer here is, some Macaws and Humans MAY prove to become allergic to birds dander and some will never have a problem with it at all.
Things can be so both humans and macaws can live with other dander producing parrots. Purchase an air purifier and humidifier, they will both greatly reduce the airborne dander. Mist and shower your parrots 2 or 3 times a week, which will keep dander to a minimum.
As with all allergies, some people and macaws may be hyper-sensitive and will not be able to tolerate any other bird in the household due to the serious health affects the dander has upon them, which would lead to death.<br><br>Post edited by: danmcq, at: 2008/11/16 13:50
