After not having had a chance to visit the Riverside nest since Monday, I was rewarded on my Friday evening visit by lots of activity by both eyasses, and wonderful views of the both parents who perched ten feet from each other for over an hour.

Having both parents together allowed me to confirm a wonderful field mark for telling the two apart.  The female has only a hint of a black band at the end of her red tail feathers, while the male has a dark black band.
