I know that i can understand if a bird is female or male by just touching their pelvic area. There are two little bonuses there. If the two bonuses are away from each other, then it's female. If those bonuses are touching each other then it's a male. But having a proplem. When touching at one of my lovebirds, i can tell it's a male because he is having his bonuses touching each other. But if i try seperate those bonuses, i can open them but not much far as the females. What is that?
