Saemma... I really believe it is innocent ignorance. Even most animal lovers don't have a clue about birds unless they have someone who has birds and has educated them. And, if the people/places that sell birds don't educate prospective owners, people are going to buy without knowing what's in store down the road -- until it's too late. People are often encouraged to get a bird or fish when they have busy schedules. How many times have you heard that suggestion from well-meaning dog and cat owners when they think someone shouldn't have a "pet" ??? Or, people who want "something" but think a bird is it because they have the idea a bird would require less responsibility?
Grrrrrrrrrrr! I could ramble on, but won't.
