You know,I think the smarter the bird,the more neurotic they can
be.I had a LS cockatoo that had an unreal vocabulary as well,he
was completely naked as well,and my Mom also has a cherry head
that has plucked for 15 years and quit growing feathers a LONG
time ago.Talks nonstop.Would explain as well why greys get as
crazy as they do...people work that way too,some of the smartest
people I know are nutty.
