I hope you heal from both wounds. Salt water heals, be it from tears, sweat, or the sea ..
I think one of the contagion things is unlikely, due to her age and lack of exposure to other birds. So if you think in time you might want another feathered friend.. many many birds need rescue, many are " sold" on Craigslist but they are still rescues, not all parrots are lucky enough to make to a real parrot rescue group...not that you are there yet , just planting seeds.. I lost my Burt The Bird and I too feel I could have done do much more, but her legacy lives on in the higher quality of life my new friends have..I hope you stay as part of the flock here. I too cried with your sweet goodbye post.
