Recently I added a third little budgie to my flock, a male named Joe. My other two are a female, Gizmo, and a male, Cujo.
Very recently, today actually, I removed Cujo from the large cage they all share to go and visit my brother's bird who he is pals with for a while.
Almost as soon as I removed him, Joe started flirting with Gizmo, as if right then was his chance or something (not that Cujo and Gizmo are a pair). She accepted it and they groomed, but now he keeps putting his foot on her back and chest, which I can only assume is a courting behavior, or maybe just being playful. This is something she often pecks him away for, but, oddly, Gizmo will proceed to crawl under his belly?
I have heard that a male budgie will place his foot on the female's back to get her into season, is this true? And is this why he is doing this? They aren't even a bonded pair though, but are closer to each other than to Cujo.
They are too young to breed (though I would love to as a hobby and for the experience), as I'm pretty sure they are about 9 months old, so now I'm worried I have to separate them right when they are getting along most.
I guess my questions in the end are why is Gizmo crawling underneath Joe, why did Joe not act this way with Cujo around, and why is he (assumedly) trying to court her whilst barely having a relationship and with her not in season?
If anyone has a clue, I would be grateful for the input
