Confused about lovebird gender

[Lucario223]

A few months back I decided to get my 6+ year old male peachfaced lovebird a female partner from a local breeder. After a while she started to show signs of attraction and eventually a very puzzling mating behaviour which made me question her gender. I'm very confused because as you can see in the video she's both lifting her wings up like a female would and brushing her tail around like a male. What kind of conclusion can I make from this?

Welcome to the Avenue!

That is her, ¨having a good time alone¨. Hens will also masturbate like the males do.

If she gets into the aeroplane position, with tail right up in the air and stands on two feet like that, I would think you have a female.

Thanks for your answer! I'll check carefully if she does that again

You´re welcome She will likely be in that position when your male is near, though if she is not interested in him, she may ¨present herself¨ to a human or toy, perch etc

This is the posture,
