I think Quaker parakeets are great birds and mine have been very pettable and interactive, less hyper than green cheeked conures in my experience. If you find a hand raised baby it will want a LOT of time but will also be very smart.
All three Quakers that I have had have learned not to poop on me but to go on paper or in a garbage can. My first Quaker would even say “potty” when she needed to go. (If you aren’t attentive you will get pooped on, though).
However, Quakers CAN be loud in a scolding, ack-ack-ack sort of way, and can be very naughty. Now that I have my own apartment and it’s usually quiet, my Quaker is usually quiet. Unless he wants something, or I’ve just gotten home or woken up, or he needs to warn me about the scary garbage truck/ Dustbuster/ vacuum cleaner/ tape measure/ laundry cart that we’re passing…
My Willow usually wants some bird time every day, focused petting and head scratches and kisses. Lucy used to like to go on walks and to music festivals and block parties. Even when she was very old she was up for a party and loved live music and singing. I have no idea if Willow would come out of his shell for such a thing as he’s much more retiring but he might. Maybe we will find out this summer.
Lucy used to arrange things and build in her cage. Willow does not. He didn’t have many toys until coming to me a year and a half ago. But he does love to be pet and is a cuddly bird once he’s settled in.
