M. Redon, 1942 Calliope Hemmerghist E. Fork Sheep Creek, 5500 ft., Kings R. Canyon, Fresno Co., Calif. June 2, 1942 Reappeared in several min. coming from S.E. & flew directly onto nest, wings beating hard NE; no feeding of young. Searched nest with field glasses for sight of young while she was gone. They cannot be seen at all from below (i.e. from the trail). When sitting on nest, kept turning head from side to side with back held at an angle of about 60° with horizontal. Could see nothing unusual up above. Watching insects (3). Flew off while I was writing the comment. Did not [illegible] in which direction she went. Reappeared in about 11 minutes from S.W. Perched on edge of nest & fed young alternately. As far as I could see, one was fed 8 times & the other twice; slid onto nest facing S.E. Noticed that between each feeding i.e. during the time that she had pulled her beak from one youngster she was preparing to feed it into the other mouth, she usually threw back her head in a swallowing movement. She sat very low in the nest this time [illegible] her head & back almost in a straight line but at an angle
