As has been the case for many years, a pair of American Dippers were nesting under the bridge over the Yuba River leading into Wild Plum campground. Only females incubate in this species, and this incubating female is nibbling on a plant used for nest lining, and waiting to be fed captured insects by the male. Incubating females are fed by the male; they also sometimes leave the nest for short periods to forage for themselves.
