There are nests at Bridge 1 and Bridge 3. Whether the females have finished egg-laying and have begun incubating is unconfirmed though i suspect Bridge 3 female has started incubating.
Yesterday morning (3/20/18) I checked out two sites where dippers have been seen but not found nesting as yet. Walked from Hersey to the park and saw an unbanded bird foraging in rapids about across from Louie’s on Guanajuato Way. It was working its way upstream but when I went farther and came back I couldn’t find it again. There was a lot of whitewash along the way but no action near the nest boxes.
Then walked from the bridge to Park HQ up to Bridge 3 but neither saw nor heard anything.
As a note: last year there were no nesting pairs on the lower reaches of our project as in previous seasons.
A report and two photos from Nick and Sooney from February of the Bridge 1 female.
Sooney and I saw this bird just below bridge 1 this afternoon around 5:30pm.
We visited bridge 1 briefly this morning (3-10-2018) and saw 2 dippers nest building. Finally saw the unbanded bird with the orange female.

On mid-morning visit to Bridge 3 saw Mr. Blue below nest foraging . The female appeared from up stream and then the pair flew downstream . I looked under the bridge and saw a completed dome nest in the box that is river left as you look downstream. It is the newer cedar box not the original plywood box. The entrance hole is to the side not center, similar to last season.
At Bridge 1 there was a couple of police vehicles and a parks truck in the lot near the trail down. I walked past and saw no dippers but did not walk down to the bridge but continued up to the fairy pool areas. I saw no dippers. Upon return the human commotion had dissipated and the coast was clear so to speak. I checked the nest box and found that a near complete moss dome (75%) filled it. As I was leaving I saw the Hersey girl with the orange bands just up stream from the nest but below the dam.
As a side note I saw a Anna’s Hummingbird female on a nest that was built on a big leaf maple branch suspended over the creek.
I spent a couple of hours looking for dippers on Thursday morning, 3-1-2018.
I started around 8:30 and ended around 10:30.
I saw 5 birds.
1) at the Fairy pond area above the park I saw 2 birds fly up stream together.
2) at bridge 1 I saw the orange female. No sign of a second bird.
3) at bridge 3 I saw the blue male and an unbanded bird flying to the nest several times with nesting materials (photos attached).
No sign of birds at Main Street or Hersey Street.
