why do you say it is a long battle? do you have experience with bird welfare?
Not exactly but you're fighting people with a vested interest in keeping the pet trade going and that means showing -
a) the birds are suffering because they're pets, and
b) the people involved only see it as a form of income and maltreat the birds.
Both of these are probably true but it means convincing authorites and politicians.
I'd suggest start local but aim national - if the banana girl can make headlines ...
