I’m not sure, but the neighbours hand raised a starling who then decided we were his best friend, and I’ve never seen such a personality in a bird. He would yell through the kitchen window for me to come get him and take him for a drive around the block. He loved the car, came for walks with me and my dogs sitting atop my head and rooting through my hair, teased my dog by sitting just out of his reach and squawking at him as a joke, and it was SO amazing, but you could actually pick his specific voice out among all the many chirping birds when he was chirping at us to come outside and pay attention to him and feed him, I had no idea wild birds could be so very funny and demanding. He’s still alive five years later and summons the neighbour to come outside and give him mealworms by yelling through the window.
