Is there an intelligence/huge personality difference in Cockatiel species???

Thank you! And yes, they do share a cage. It's a pretty big cage so they have plenty of room to move. I'm usually home so I pretty much spend the whole day in the room they're in before they decide it's bedtime around 5-6 and then I leave. (before the time change, their bedtime was at 7, so they started going to bed around 6. Now it seems like they're ready to sleep by 5!)

I'm pretty sure Domino is a male because he struts around doing his heart wings, but I'm not so sure about Yahtzee. Some days I think it's a boy, and other days I think it's a girl. Domino keeps doing heart wings around Yahtzee, but idk if he's trying to impress Yahtzee or me, or just trying to show he's the dominant one. I think they're both still too young to be thinking of mating, right??

They're a lot more sociable now than when we first got them. (They both came to me and climbed to my shoulder by themselves!! ) I guess I just need to be more patient with them. It's just so weird how different they are.

Thank you ^^
