From a) to b)...

Let's start with a Cape parrot on an atom - an atom she doesn't want to be on.

What happens?

She jumps/flies off.

What happens next?

Well she lands on your arm. Great, right?

No. Not when she's in a "mood" - you can see the glint in her eyes - and what she really wants is your fingers, hence why mine are mostly tucked in (except for my poor thumb).

Putting her down anywhere other than where she wants to be results in this starting over again.
