Help me find out my cockatiel’s gender

[Nea]

My cockatiel is around 8 months old. I gotten her at 3 months. She’s a pearled cockatiel. Grey with white spots. The hair part is yellow but her face is white. She’s been acting like a boy recently and she picks up on stuff fast. She knows how to say peekaboo and hide, she knows the if ur happy and you know it song, she also learned to say hi in Arabic and she’s been giving us kisses. And I’ve seen her walk and bring up her wings like a heart , i heard only boys do that?. I’ll attach a picture of her. She’s a boy right?

I would say boy based on behavior. Also male Pearl's molt out those Pearl markings as they mature. Females retain them. He's very cute.
