I came across a site that has lots of information articles written by Nikki Moustaki, at:
I didn't read all of them yet. As well as the article links in the centre panel, there are more links on the left side panel. The top one, under "Behavior Aricles," is What? I Can't Hear You Over My Parrot Bird Vocalizations And How To Deal With Them is what took me to the site initially, and I did read most of it.
The articles cover everything from Chic Chick Decor: Designing with Your Bird in Mind to bird-specific articles on the Grey, Eclectus, Budgie, Amazon, Canary, Conures and Caique.
Hope you enjoy!
