I agree with this.
Especially since Quakers have been know to have nasty attitudes.
My sister's friend has a quaker(came from the same parrents as my quaker did, but this one is a year older) that is absolutely evil.. and eventhough my quaker is still young, he lets visitors hold him without a problem.
It completely depends on the bird.
