Male or female?

It is born on 06/06/2019, I saw some big feathers on the ground so I guess 1st molt happened. It had pearls and still have them. It has a male DNA test, but I have read about cases with wrong DNA test. Photo 3 is older and photo 4 is of these days.

Could it be a female because it still has pearls?

Thank you!

Maybe I'm wrong, but your bird not even being 6 months old I doubt the first molt has happened, however you are correct that the pearl pattern will pretty much disappear in a male, but usually 10-12 months. If you have DNA proven gender that's your best bet at this age, and mine that were DNA proven have been 100% accurate. Looks like the same mutations as my female, lutino pearl pied was the decision we have made, unknown hidden genes may be possible too. Either way, beautiful birds!

I am asking because my younger bird, born at 27/06/2019, which was supposed to be a girl from the way it whistled, lost it's pearls some days ago, so I believe it is a boy. But of course every bird is different.
Thank you!

Was it a screech like whistle or did it carry a recognisable tune? My sister made that mistake with hers, not DNA proven of course, but when I met her bird i told her I believed it was female, after two months she is believing more and more that I'm right. The picture you just posted, looks like a whiteface pearl, and it does look male, do you have DNA on the younger one as well? My female at a very young age didn't do much more than chirp and "hungry cry" I never heard a whistle come out of her till she was about 6 months old, even then it wasn't even a simple tune like wolf whistling, my males on the other hand will sing, mimick, head Bob or as I call it head bang, knock on cages, and both will argue about stepping up, my female won't leave me alone long enough to get the food bowls out. In person I'm pretty good about studying the body language and subtle hints with about a 95% rate of gender identity, based on what I've seen and read about here, I'm guessing you have two males, not all bad unless you are dead set on breeding, but you have a few years before that anyway. Two males can create an inseparable bond just like they will in a male/female pair, even my 3some meeting for the first time went well, cockatiels are very social.
