Thank you for the feedback on foraging. Yes, I have tried some foraging toys. I have one in there now. I always try to rotate the toys around. However the paper on the food is a good idea, and maybe I will see if there are more foraging toys on amazon or the like. It is unavoidable in my schedule that there will long periods of time where he is alone in his cage. the toys seem to keep him busy for minutes or an hour, but the periods of time are much longer than that sometimes. Ironically, sometimes he plucks less when I am gone for a couple of days. I bought a senegal parrot in part hoping that at least the calls of another bird in a cage across the room will keep him company a little.
But one way or the other I am committed to that bird. He's been with me about 15 years now since he was a baby.
