Подробности наблюдения
Minimum count by twos. Significant groups seen in flight numerous times; groups also seen perched along the stream frequently, including at least 10 near the reach 3/4 boundary, and at least 10 (probably more) ca 100-200 m above the diversion much later. Count based on groups seen flying upstream, somewhat high (many times shrub height) between 0814 and 0818. Groups counted of 30; 8; 8; 6; and 20. Groups of up to ca 30 seen in flight several other times during the count, but robins were moving in both directions and I did not attempt another count. Could be a substantial underestimate. Suspect they were feeding on Chokecherry fruits, but I did not confirm this positively. In the area NW of the diversion, I saw several robins on the ground, presumably foraging for something.
