hi everyone ! i need your help
my first ever male bird, who is now 1 year and 3-4 months old, keeps doing this very strange position some times a day, maybe even 3 or 4, but not every day. im guessing it's a normal hormonal behavior... since before this, he used to drag his butt left-right with his tail down on this wood swing.
it's very strange to me because when he does this position he keeps on doing very short monotone whistles, from a good minute, until he stops and eventually sings or puts his wings in the heart position while going up and down with his head. (yes, after he does these dirty things he is happy and sings a lot lol)
also, we bought 2 days ago a good female cockatiel, and my male bird is really interested in her (ex: trying to bite her feathers or tail but playfully), but for now we're not going to put them in the cage together yet. and even with her, he still does this behavior. in this exact time im writing this, he is doing it for the third time, lol.
should I do something? is it even normal behavior?
thanks in advance <3
