This picture is the result of patience and luck. I have set on this nest 5 times for at least 10 hours total before I caught this bird outside the nest. Generally she would just look at me from the shadows, and when I relaxed momentarily, she would fly off and I came up empty. Today she flew away and came back. I take that to mean that the babies are now hatched. She seemed feed them, but I am only guessing.
