About the dust... It's all relative. Depending on where your birds are, you might notice dustiness or not (big open living room vs smaller room with dark furniture for example)...
I've been wanting to post a thread regarding what I've personally noticed about this very topic. I'll put in in the General Parrot Information section . We all hear Toos, tiels, and Greys, but you might be surprised at who are the "second" most dusty species!
