Bluebird Park 830hrs:
…drove up to the top and walked down as per usual.
Two dippers were seen in the Granite St. swimming reservoir. When we first saw them one was on a rock on the east side and another was swimming and foraging nearby. Both birds were close together for a short while even sharing the same rock. One bird sang softly. One bird flew off up stream after the other moved a bit closer. Not really antagonistic behavior but could not say they were a pair. One bird appeared from the dark breast and dark mandible color to be an AHY bird (after hatch-year/so over a year old). The other bird I never got a good enough look to say. When I returned after the walk to retrieve my truck I did not see the birds in the reservoir and did not look upstream.
A lone bird was spotted foraging (successfully) between bridge 3 and 4. The bird kept flushing downstream ahead of us until we lost it below Bridge 5. It appeared to be a HY bird due to its light breast and light colored lower mandible. It called just once when we watched it and not loudly.
