The nest is a crowded space now as the babies test their huge wings. Mama was in and out bringing new branches. The babies seem to also arrange the new housing material. I don't know how their perception changes if they watch something upside down, but it sure looks funny. They look like babies, but every once in a while you get that raptor stare, not entirely babies anymore. If you go back to the blog images a week ago the growth is astonishing.
