Nov.21 Bodie, Mono Co., Calij (cont.)
In route we saw a small flock of sparrow sized birds flying low over the sagebrush, one Rough-legged Hawk & one Black-billed Magpie. Earlier we had seen another Buteo (not Rough-leg) that resembled a Swainson Hawk. We returned to Bodie at 1:30 pm & ate lunch. A Horned Lark flew over [n.e]. After lunch we hiked back up Green St. (east) to the vertical mine shafts to see when & if rosy finches would return to them.
I went to shaft 5 & Marr. to shaft 4, both arriving by 2 PM. Rosy Finches appeared at both shafts at 2:30 pm arriving from the south or southwest (not from the west over Bodie). At shaft 5 about 40 birds arrived at 2:30 pm & circled over my head (I was located 40 yds to the n.e). Some flew up & out of sight to the north. Others land 20 yds west of me on a shaded 30 ft. east facing cliff. Others landed within 10-15 yds. of the shaft. Birds circled & landed often but I saw none enter the shaft. After 10 minutes all the activity ceased & about 10 birds were perched on the nearly cliff face. No other birds were in sight. None of these birds were the Cascade race (L.T. littoralis) or L.atrata.
I could not distinguish them further, ie they could be dawsoni or tephrocotis. At 3:00 PM one bird flew from the shaft & another hopped along its lip. I hadn't seen any birds enter or approach the shaft but there were lapses in my observation of the mine entrance. The birds on the cliff remained there preening, feeding & hopping about or just huddling in a niche. There were several brief
