At Bridge 3 I saw both dippers below the bridge. The female who is the notably darker and smaller bird was sitting on a rock below the nest.The male was foraging in the creek. The nest appears complete and I suspect egg laying may have begun from the way the female was staying close to the box.
At Main St. I saw both birds and they appearred to be putting the finishing touches on the nest. I saw the female bring some pine needles into the nest and the male also came to the box carrying some other material.
