Mr Redon, 1942 Calamops Hemmingford- E Fork Sheep Creek, 5,500 ft, Kings R. Canyon, Fresno Co. Calif. May 31, 1942 her about 50 or 60 yds. away, at almost the level of the trail, stopping in mid air, then flying down & stopping, then up & stopping. After perhaps 30 seconds of this, she was lost from sight. (Insect hunting?) On her return she perched just a second on the Alder, then she stopped just an instant as a branch fell above her rest, perched at nest edge & fed young. Twice she prodded in one direction, with forceful pumping motions but failed. I could see the nestlings heads surrounding hers. It is now a pale yellow & still short & broad. I could not estimate the length from what I saw. Then she raised her head into the air and made a sort of swallowing movement with her throat. She now turned a little to the right (her right) of where she had previously gone down & once more the spasmodic pumping movement occurred. The suns & clean feather down into the nest now so that only a quantity of an inch of her head per low at its lowest point in the process. She settled again on the broad nest, now facing the NW and turned her head as I turned mine to look at her. Time=11:05 and the sun is on her now. Stayed on rest 20 min. Looking around, raising her head occasionally; she flew NW & down into Cats gorge again-
