Davis 1948 Red's Meadow, 750 ft, Sierra Wall for, Madera, Cal. July 15, 1948. One remained about 40 minutes before flying, the other about an hour. From time to time, small groups of birds, from 2-4, would come out and fly about, always downstream, & mainly over the west bank. The last flight involving 12 or more swifts took place at about 11:45. No others were seen from then until 1:20, when we left. I estimate that from 15-20 birds were seen, that most of them hung up behind the falls, & there were several birds that seemed to be paired in flight, one closely following the other, through all of its twisting turnings. That some of the swifts were outside the falls was evidenced by I seen on the sheer rock wall on the west side of the falls. Noted a dipper flying over Rainbow Falls and perching on the west wall at 8:20 a.m. And on both occasions of our visit to the falls today saw a white-breasted nutchatch carrying food to a nest cavity in a dead red fir, the entrance hole being about 10 ft above the ground.
