You're all wrong.
Try my budgies.
We have: The two old men, who eat and sleep. One of them is always asking for more food if he thinks there isn't enough. The other you can almost see him rolling his eyes and saying "there's plenty". They're both puffed up with their heads under their wing after lunch.
The girl: In charge. She's very quiet, says very little, but if the others try to stop her getting what she wants they'll flee at her just walking towards them. She also is the most agile and can be found climbing over places the others have given up getting. If she comes out, she just makes her way to the top of the cage and watches. She's standing at the moment on the top of the swing and watching the others.
The boys:
#1: The chewer. Likes to try and chew everything. Chatty in the morning especially and likes to be handled. Will climb onto your hand on demand and sit on you. Likes to be with others, but preferably a little higher than them. Has gone on the highest swing to have a doze, but her tail is within reach of...
#2: The mischief. Can't manage to get on a swing easily and normally ends up hopping round with one foot on and the other off. Always chatting, getting stuck in places upside down. Will pull the others' tails and run away. The most likely to object if any of the others come to share the food dish. The most likely to run away if the others stand their ground.
When he comes out he flies round and round and explores the bookshelf.
Also loved the mirror to a point we took it away as all he wanted to do was talk in the mirror. Is currently banging a bell and shouting at it between nibbling #1's tail.
