Before you contacted your local animal rescue try giving your local avian vets office a call. They will be able to tell you the best place to call in your area. Not all animal rescues are able to accommodate large parrots. Quite often they are forced to keep them in the same rooms as other caged animals including cats.
We have members all over the country here and in other countries as well that may know of a good resource in your area. Many of the people working in avian rescues are members here. If you want to post where you are located, best to post what major city is closest to you.
