Hi! My name is Amanda, and Sonnee is my 2-year-old cockatiel. We've been calling Sonnee a girl for 2 years, but now I'm curious as to "her" true gender.
Sonnee is a pearl-pied. I know male pearls will loose their pearling, and I also know that pied cockatiels cannot be sexed by plummage. But what about abird that is both pearl and pied?
She still has her pearling (though it might be a little bit less than when she was a baby), and bars on her tail feathers. Her face was pretty yellow even as a baby, but it might be a bit more yellow now than it was.
As for behavior, it's hard for me to tell, as Sonnee is my first cockatiel. (I had a female budgie a few years ago (sexed accurately by the color of her cere), and she was as vocal as any male budgie I've known..) She seems quite vocal, and really loud, but she's often very quiet as well. She loves to whistle. She tries to mimic some sounds sometimes, but honestly she's not very good at it (she can copy simple whistles, but only other thing she's tried is the sound of the phone when buttons are pressed).
Does anyone have any insight into this topic? I don't plan on breeding Sonnee, so "her" gender isn't really all that important, but I would like to know, just for the sake of knowing.
