Two Indian Ringnecks

Hello, I’ve recently got two Indian ringnecks, I’ve had them for a week on Sunday. I’ve been told there is one male and one female, the female being around 6 months and the male being around a year or so?

The female seems very happy, moving around the cage, hanging upside a lot and is slowly becoming used to me, whereas the male he seems to sit on his perch more and just fluff his feathers up.

Is there a reason behind this as it’s concerning me as the female is completely different.

I will attach an picture of them both.

Thanks for any advice!
