Are these gender related or personality based differences between my male and female cockatoos?

Question

Curious if my following observations are more likely age/raising/personality differences rather than gender in my 6 year old male (boo) and 2.5 year old female (Swift) goffins:

1) Boo (the male) collects treats, food, and "stuff" in empty bottles. Swift puts the same types of things in her feathers.
2) Swift (female) reacts to threats by tapping her beak, poofing her feathers, screaming without end, and retreating to a covered cage. With the same stimulus, Boo retreats to the door top (highest place in the room), screams a few times, poofs up for a second, and then observes.
3) Swift, at 2.5 years is already talking more than Boo ever has (he is 6.5 years old). She has a HUGE range of whistles and vocabulary! Boo uses his body language and a smaller vocabulary to communicate the same things (food, cuddle, alarm..).

Both birds are extremely cuddly and friendly with strangers (though Boo is more gentle and I trust him NEVER to bite). I've had Swift for about a year and Boo all his lif

PS: Vet checked on the gender thing! Boo is a boy and Swift is definitely a girl!

Answer 1

Females are said to be very determined and a little bull-headed about getting their way. They play with toys all day long. Females seem to be more loving of the other birds in the home than males

Males like to pull the tails of other birds in your home and are said more often by owners to be very mechanical. Males are not said to love the other birds in the home as much as female

Answer 2

after owning many hamsters I would have to agree with those who say males are more laid back, in general. There are always exceptions to the norm. Before I switched over to rats, I remember my male hamsters were much sweeter. I have one female right now (rescue) and she's okay, but not outgoing like the males were.
