recently i have noticed my male budgie sometimes lies on the top of the cage on his tummy. he doesn't do this too often, i only saw him twice so far and it's been two weeks in between these behaviors. i have looked this up but wherever i went, it was female budgies who were in question and it usually had to do with nesting.
he eats regularly and seems cheerful throughout the day. he chirps as much as usual (which is a lot.....) and plays with a female budgie i have.
i took pictures of both when he did it two weeks ago and right now:

i'm just a little concerned whether something is wrong with him, as i have never seen a budgie do this before (having had a few more in the past). i would just like to know if he's ok and not in pain.
