Haha, thank you!I've been wondering about it for a while, but whenever I'd pull out the camera, he would always stop.
He can be quite the brat though. Budgie was trying to sleep earlier, and he stood perpendicular to her so that his head was about 2 cm above her back and started singing and wouldn't stop. He runs away whenever she tries to preen him after a bath, but apparently he's suddenly her best friend when it's bedtime.
So cute! My Niko does the same thing when he sings to our feet, our kid's character blankets, the dog's yellow monkey toy, or when we call him 'lover boy'. I never knew it was called heart wings, even though that's what we call it.
Yes, definitely heart wings, congrats! But even if he wasn't doing that, it's pretty obvious he's male by how well he whistles. Yes, some females whistle, but for the most part, if your tiel whistles well like that, and often, it's a good bet he's male But the heart wings confirm it
I started trying to teach him to whistle as soon as I got my cockatiel research done with. Thankfully, he picked up pretty fast, and every time I try to teach him to say something, he learns it as a new "come here" command. Earlier today I walked into the bedroom to see my sister playing with him. As soon as he saw me, he started walking across the bed, but my sister picked him up. All I had to do was say "Shiraarat, come on.", and he flew out of her hands and over to me .
I think it may have to do with one of the cockatiels at the bird store we bought him from. It knew a variety of whistles, and sounded very human. I spent five minutes trying to figure out where the store attendant who was whistling was hiding, lol.
