Birds are so different then dogs because they choose who they like. You have to earn a parrots trust, respect and friendship and sometimes its just a matter of chemistry. My birds all have different realtionships with each member of my family. They seem to treat me like the mom and the hubby is irresistable to all of them and they treat him like a boyfriend.
As far as cockatoos go, I think the males are more rambunctious and rough and tumble. My cockatoos are both girls and while the males are known to be more aggressive when they reach maturity its not unheard of for females to also become aggressive. I think more common though amongst females is that they can become phobic, or begin plucking and mutilating when they reach maturity. This is not all cockatoos, some will never become aggressive, pluck or mutilate but this can and does happen to some.
