I am curious about something. When I feed Timber anything off a spoon, and sometimes when he is eating something he is holding, he bobs his head several times. I remember reading something about this being a feeding behavior (from feed bags I think)? I've never had a baby bird, so am just curious about this. If so, do they do this all of their lives? I was told he is 4 or 5 years old. If this has already been asked and answered I apologize!
