I've tried looking an several sites to figure out what the heck it means when my bird lifts one wing and one leg on the same side.... they say its usually a greeting. Or that the bird is trying to warm up it's foot... (?) But s/he's not really doing it as a greeting. It's after s/he's already been out of the cage for awhile, usually perched on one of our hands or arm. S/he did it once after being returned to the cage. What is up with this motion??
