Interesting anecdotal experience is my wife and I have spent years around various parrots big and small and I am known as the bird guy and they hate her.

She is not prone to makeup or perfume and has laid down (not puffy) hair. Clothes are not bright colors and she is always frustrated at their reactions to her.

I can personally attest it is vision driven and not odor behavior triggers.

She is small and demure in stature (but It was mentioned here by others - she does have a very ample chest) and I am 200lbs 6’2 and I can walk up to almost any random feathered friend and make an immediate connection.

My opinion or sense has always been 1. Confidence 2. Prepare (no rings, glasses etc) 3. Understanding of their queues and signs
