I have never worked with a bird who wanted to regurgitate as much as Paris. She does it in her cage when I reach in to give head scratches,through the bars, sitting on her perch when I walk by , with in a minute of any interaction she is head pumping. Do I need to worry about this? As soon as she does it and manages to get it on/near me she is good for the rest of the day. If I keep walking away and not letting her she gets almost desperate. Should I just let her do it in the morning and be done with it for the day?
