Maybe I have a defect tiel. LOL.
The cockatiels were on a different side of the house, and on a different floor from our GCC. The GCC and tiel rarely have any contact at all - they can't even hear each other. (both rarely scream.)
Also my tiel is kept in the same room, now, as my cockatoo. They don't have contact, but they can see and communicate with each other. My tiel loves my cockatoo (sidles up to my too, tries everything my too eats, mimics my too) - but my too doesn't like her. I take them out separately and luckily neither gets too jealous.
