Beats me. My bird is domestically bred.
Their nature is to pair off, preferably with a bird of its own kind but, lacking that, it will bond to its owner, a bird of another breed or even an inanimate object (especially one with mirrors). If you've ever met a pair of bonded birds, they typically hang out with each other *all the time* like newlyweds. That's what they want - constant companionship and, unfortunately, we humans want more in life than to make longing looks and share meals with a bird all day. I live in an apartment with just one bird, a small macaw. I know she is bonded to me but I also know someday I'm going to have to break her heart and find her a new home (for her own good). The one thing about my breed of macaw is that they are adaptable and accept change better than some other breeds. She may grieve over it for awhile but hopefully, I'll find her a home where she'll get more attention and companionship than what I can give her.
