They're little superstars in Brooklyn. If I'm not mistaken, there are now little tours to go hang out around where they nest.
Also...from firsthand experience Quakers are little escape artists. I mean, aside from the doo doo bags that go and release their poor and more than likely abused critters out into the "wild" of their backyard, you've got a lot who want to keep the pet, they just don't know how and the animal ends up escaping somehow.
Within the first 2 months Sky had learned how to escape his first flimsy little cage. Not even through the main entrance (he couldn't). Instead he would lift the latches of his food/water bowl door area thingies and out he'd come. Now, he
rarely ever did this (possibly once or twice), but the first time he did we had all turned away for a moment.
It was a special circumstance. We were at a cousin's house with him, and he did not like it at all (he's never tried to 'escape' at home). He wanted to be with me, but everyone kept pestering me to 'leave him alone' (as if he really wanted me to leave him alone). He was sitting in his cage looking unhappy. Looked away and looked back and he was out of his cage. I didn't remember him being out, but decided I must have let him out and forgotten. Except that the main door wasn't open? So we put him back in and watched and lo and behold he escapes his cage right in front of us. They're very determined when they want to be!
So, in addition to being quick to escape, many people leave their birds flighted without teaching them proper recall or anything. In some cases, people have the time and resources to ensure their babies don't escape, but in other cases, inexperienced owners just don't know what they're doing and bam, you've got a case of feral birds on your hands.
So combine an inexperienced, careless owner, with a flighted Quaker Parrot and you've got a recipe for disaster. And I think some states are just looking out for their agriculture and native fauna.
The best thing about having them here is seeing them alongside pigeons. Two pests side by side!
Also the best thing about them being legal here is me getting to happily and safely keep Sky
