During a late afternoon visit to observe the nest box action, had a wonderful opportunity to see the chicks moving around the outer ledge of the nest box.  As happens at this stage of growth, there was lots of wing flapping and movement by the chicks.

Of particular note was watching the female go out on the perch a number of times and show the chicks how to do so.  she demonstrated how to balance and not fall off.  Then she took off into flight in to the west.  As she lifted off, her talons remained out, not tucked under in normal streamline fashion.

She was making a very short flight to a nearby rooftop to show the nestlings how to prepare for first flight!  she remained on the roof for a few minutes and then took off in a flash.
