Tonight, the young ones were more aggressive about coming to the edge of the cavity.  There are definitely at least two nestlings. 

Adult whinny and hoot-hoot vocalizations were heard.  A raccoon seemed to trigger the hoot-hoots.

Feeding of what may be moths, continued as their were frequent flights between the trees near the West Drive’s street lights, an interim stop on top of a broken sapling ten feet in front of the nest and the cavity.  One pictures of a nestling shows the food, but it is too blurry to see if it is definitely a moth.

The male was reported to have been out of the cavity all day, and the female left just as I arrived.  They both would have been fun to photograph, but I concentrated on the cavity and its current jewels.
