Rebel made it back down to the nest after his tree explorations yesterday. With both of them calling, I went out for the Nest Watch. Rebel's call has a deeper pitch and I could hear it, but couldn't find him. Yankee was standing on the west side of the nest.
When I got to the good spot in the back yard, I could see and hear Rebel sprawled out in the nest. All that climbing yesterday must have tuckered him out.
