Comments: At least two begging juvenile CANW on a boulder along the lower scarp (river right). Was not able to get a clear enough look at the third bird to determine its age, but the chatter trailing end to its call (distinct from the singular, but oft repeated, calls of the other two) leads me to believe it was a distressed female. All three had a distinct white throat/chest.

Comments: Single adult vocalizing and flying past us through the river canyon (in an upstream direction).
