There isn't any solid evidence.

That's not evidence, it's a belief, guess, assumption, hope, hypothesis, whatever you want to call it.

I don't say that birds aren't or cannot be emotional but that there is no evidence for this. Therefore we cannot base our interactions or understanding of them based on something that cannot be demonstrated. Training, interaction, etc may possibly appeal to and work with their "emotions" but we wouldn't know that there is emotion to it. This is why I focus on a behavioral approach where I do something and the parrot's behavior confirms the interaction.
Without a doubt there have been times when the parrot's behavior was uncooperative, bitey, moody (changing from one thine to another unpredictably), lethargic, excited, etc. These are observable and comparable to behavior at other times. However, they do not demonstrate emotion. There may simply exist other operant factors we are unaware of, instinct, or physiological changes that trigger these without any existence of emotion whatsoever.
Really, I think the vast majority (or all) of emotion lies on the owner's end and is being projected onto the parrot. Owners want to feel that their effort isn't all for nothing. They want their parrot to be happy and love them back. I can live with knowing that they couldn't give two shits back about me and that they see me as nothing more than a sucker who gives them stuff they want. This is because my love for them is unconditional. It's my own thing and unimpacted by their emotions or lack thereof. I think it's counterproductive to assume or believe that they have emotions because it distracts from more objective approaches that really do find results. Soooo many people will say "my parrots just hates me so it bites all the time," when really all it might take is changing the approach to make being with the person more reinforcing. It doesn't mean the parrot had any feeling toward the person good or bad, but positive reinforcement solved it. Meanwhile assuming it is emotional hatred causes people to give up trying because they think the emotion cannot be changed.
