AoA - Friends, can anyone having experience with Alexandrine/Raw parakeet tell what's this behavior and does this say anything about the bird's sex?

Sorry if the video isn't clear enough as I had to capture this from behind the window so I didn't distract them. I'm sending a couple of still images of the same bird as well.

Appreciate the assistance.
