My childhood freind had a Sulfur-Crested Cockatoo that would follow him to school and just hang out until he was out for lunch. Sometimes he would find his way into the classroom, he was a super smart bird and knew how to get the windows open on some of the rooms. My mum helps with rescue birds sometimes and now has a Gullah, which for anyone familiar is a pink/white cockatoo very similar to a sulfur-crested cockatoo. He's so smart, knows tonnes of words. songs and situations, and knows that when the cat shows up he can refer to it as "Pus pus pus". The YouTube channel MakersMuse 3D printed some puzzles for wild birds to solve on his porch, it's really remarkable to watch them figure it out: https://www.youtube.com/watch?v=A5YyTHyaNpo https://www.youtube.com/watch?v=A5YyTHyaNpo The Australian Magpie is also extremely intelligent, surprisingly they're not part of the Corvus family but they are very, very similar.
