Although this is not a scientifically based research project, when trying for 100 species in Josephine Co in the month of January (managed to find 103) I can normally find a Dipper along the Rogue or Applegate Rivers. However, this year with all the rain the river levels were really high and the water was pretty muddy. When I check the locations I normally have found Dippers along these rivers, none were located. None were found at the mouth of streams entering these rivers either. I had to go up the Caves Highway (road to Oregon Caves) about 16 miles to find one along Sucker Creek (near Grayback USFS campground), which had a relatively normal flow level for winter (water was clear). The second place I check, there was a Dipper.

Subject: [obol] Dipper Question
With all the rain we have had this year, the rivers are continually swollen, and I have not yet seen a dipper where I would normally see them. It has been my understanding that when the rivers are high, they go higher up where the water is clearer to feed, returning when levels have decreased. The other day I was birding with someone who thought the opposite - that the excess water pushed them down river. I don't remember seeing dippers anywhere where the water was slow flowing. Anyone actually know that dippers do when the water is high?
