Shadow was completely quiet the entire time until I climbed up close to her. That is when I heard her cry for the first time, and it was not a happy cry. She was scared. I reached my hand out to her, and she reluctantly sniffed it and then let me touch her. A gentle pet on the head and back was all she needed to be fully reassured that I was friendly. With that introduction out of the way, she was very friendly and perfectly trusting of me.
Back on the ground, I handed her to Keith, and he took her inside to release her. Shadow had been in the tree only eight hours or so, so the task of getting resettled into her home was an easy one. She was soon dry and settled in for a nap on a pile of towels, and Keith took a picture of her (below) and sent it to me.
