As you read the many threads that are posted here you will see the term body language used over and over, My bird bit me because I did not read his body language so it`s my foult. My grey put his head down for a scratch and when I went to scratch him he bit me. How often have you read that.
We may not always read their body language but they always read ours. They know how to play us and they do it very well. They can sense our moods and know if we don`t feal well, or we are happy,or sad.
They are more tuned in to us than we are to them and they don`t ask for much just respect. You can look at their eyes and tell whats on their mind but if you look into their eyes you will find they are looking back.
When ever I look into my birds eyes I wander whats going on in there, what am I mising, whats on their mind. I always have the feeling they know whats on my mind.
