When I think about my birds, certain things occur to me, like:
1. They want to feel safe
2. They want to feel loved
3. They want to have fun
Of course, they require much more than just those essentials (such as yummy and nutritious food, an adequate and stimulating living environment, etc.). But I would say that those 3 things should always be at the core of a pet bird's world. And it's surely not a lot to ask.
