I know I've already made a post called this but that was like forever ago, so I'm making it again.
Anyways, this book is really good!
There's a movie of it too on PBS. It's written by a man who feeds the cherry-headed conures who live in California (they're wild). He has some stories about the birds that are really touching.
It's also about his life a little, which is interesting because he used to be homeless, and he still does not have a job.
Here's his website: http://www.markbittner.net/
