Holy S#!T!!! pretty much the SAME thing happened to my Lilac Crowned Amazon this morning. We were sitting outside, I in my chair, Bacci directly in front of me on his perch. All of a sudden, his feathers went FLAT to his body. He was completely sleek, and staring just straight ahead. He was completely un-responsive to me. Would not react to my speaking to him. Would not step up. I was TERRIFIED. I finally pried him from his perch (something we NEVER do), and his little body was so stiff . I brought him inside, and placed him atop his cage, where he perched, but still, staring and unresponsive. I was panic stricken, and while my mom called the vet, I took a peanut, and showed it to him, his eyes pinned, but he made no move for it. I put it near his mouth, which he opened slightly.. I put the peanut in his mouth, he took it in his hand and I ran to get dressed. I came back, and he was sitting in the same position, staring, with the peanut in his hand. I showed him a sunflower seed. Eyes pinned. I put it in his beak. I ran to collect shoes, money, car keys, and when I came in to collect him, he was still sitting there, stiff, motionless, peanut in one hand, seed in his beak. Upon seeing his travel carrier, he moved his head, and my boyfriend was able to target him with the stick & clicker a few times. It was only after he was in the car, that he got back to normal, playing and looking around. By the time I got him to the vets office, he was perfectly normal again, and the vet could detect no obvious problems. On the car ride home, Bacci was sitting on my hand, chirping & hooting along to the radio, as happy as ever.
