Dunsmuir Hedge Creek Falls Dipper family

On Thrusday June 25th I made a stop at the Hedge Creek Falls park in Dunsmuir off of HY 5. We walked the trail to the falls and found an adult American Dipper. The bird was making frequent flight's into the falls itself. We did find the nest was to the left of the falls maybe 15 feet up on a ledge. It is a large moss dome shaped nest, maybe 10 inch's at the base. There were two immature American Dippers almost full grown hanging out of the nest. We checked again Friday evening at 7PM and discovered two adults feeding the immature birds. We checked again Sunday at 3 PM and the nest was empty and no adult American Dippers could be found.Rich CiminoAlameda County
