The next morning we were able to get Sunny back because he was flapping around and calling out for us - he was really scared and trying to find his way into his broken aviary. No sign of Cher.
The King parrots circled for a few days until we were able to salvage their aviary and with the help of friends we constructed a new aviary for them and propped the door open. The male Kingy came home first for a feed so we put him in a cage inside the aviary and he called for his mate to come home. She is crafty and circled around the nearby trees but wouldn't come down. In the end I hid in my laundry with a long rope going out to the door of the aviary and waited. It took 2 hours for her to be confident enough to fly in and I got her!! This is the 4th time the Kingys have escaped now. They always come home in their own good time. We have joked about just leaving the door open and just provide them with food and a place to crash like teenagers.
I still can't find Cher. I think she's long gone. I'm upset about this because she was a green split blue that I was hoping to cross with Sunny who is a yellow split blue.

Such is life.
