The two eyasses were very active in the early evening. The mother left them alone most of the time I was watching. (Red-tailed Parents feel comfortable leaving there kids alone, once they are as old as this pair is. I haven't figured out triggers the change in behavior. Is it a change in coloring, the size of the eyasses, or something else?)
If you haven't visited the nest yet, make a point to see it this weekend. It's about two blocks north of the Boat Basin Café.
