I recently rescued an 11 year old female umbrella cockatoo named Marshmallow. Her previous owner had passed away, and she was at an animal shelter. I brought her home and acclimated her to her new surroundings, but she’s been doing something a little strange recently. She tries to give me food. I have given her some sliced mango, peanuts, and apple chips, and with all of these, she will hold it in her beak and try to put it in my mouth. She does not try to regurgitate before doing this, but it’s like she’s trying to feed me. Can someone help me understand this behavior? What does it mean?
