cockatoo species

at my current point in life i have no time for another bird, i’m too busy with nursing school and don’t wanna bring another baby into chaos, especially one as delicate as a too, however i’ve been saving and wanting one for years i plan on getting a HUGE cage, plenty of toys, basically the works...

Is there a difference between male and female Galahs when it comes to behavior? For example, ringnecks and cockatiels show distinctive behavior where males do a “dance” with heart wings and females bend and chirp when trying to mate. what about cockatoos, and RB2s in particular?

I tried googling, but didn’t find the exact same parrot. Is it a hybrid? :D This is my friend’s in-law’s parrot, for some reason he doesn’t have nails :(
