Photo by Dave Location: Centralia, WA Eye pinning parrot: Blue and gold macaw "Tiko"
In this photo Tiko the macaw is pinning his eyes (also referred to as "eye flashing"), this means he is excited about something, which is when all parrots pin their eyes. Eye pinning also indicates when it's most likely a bird will learn something; like a new word or phrase. If it excites them, it has their attention.
Eye pinning or flashing is the action of when the bird dilates his pupils from large to small (contracting the pupil) so you will notice the pupil go from big and dark, to tiny and out again and back to small. My blue throated macaw Jinx does this action right before saying, "hello", while he also tends to bob or twitch his head a bit right before speaking as well. These are signs he is getting excited.
Eye pinning can mean a variety of things from leading to happy behavior, like I described with my talking macaw, to leading to a bite or over stimulation (aggression). Usually there are other body language signals that accompany the eye pin that will tell you which one it is. With Tiko, if he puts his wings out and pins his eyes, he is likely going to scream as a means to ward you off. If he is standing tall and pinning his eyes with his feathers flat, he is likely excited to see you and about to talk on cue.
It's important to pay attention to the other signs that accompany eye pinning so you know what's to come.
