Are these birds like your bird?
We went to the Garden Of The Gods on Easter Sunday afternoon in Colorado Springs and a young lady had her two birds there, and jogging with them on the trails. They were very tame. She was training them to sit on a big stick she held while she jogs with them.
They were sitting on a fence here, while she rested.
These had a few orange feathers under the white ones on top of their heads. They could raise those feathers up and stick out.
