My newly adopted (23 years old) green wing macaw periodically throughout the day will step on some of her wing feathers(causing shredding of her wing feathers). She lifts her tail and squats and yells rhythmically. I am guessing this is some sort of mating behavior and it does not bother me except for disfiguration of her feathers. is there anything I can do to discourage the behavior? I don't want to reinforce it by going in to her room every time it happens. Thank you for any help and suggestions!
