She lived with me for two years during an illness and was rather tame. So it is also possible that someone got hold of her and is keeping her as a pet. In any case, Connor is, once again, without a mate. The bird had been alone and flying free for two years. The bird was already wild and free.
Parrots are very social and they loathe loneliness.
He has fit in very well. Whenever I have released back into the flock birds that I've cared for, they have always had to fight their way back in. Manuel only had to deal with a minimum amount of fuss from the rest of the flock. Perhaps because he was already at full strength. One valuable thing for the flock as a whole is that this increases the size of the available gene pool.
