M. Redon, 1942 Calliope Hummingbird E. Fork Sheep Creek, 5500 ft., Kings R. Canyon, Fresno C., Calif. June 1, 1942 Appeared in oak near nest tree. Perched in sun— light and preened, scratched, fanned tail etc. I was not watching as she entered nest, but I looked barely 2 seconds after and I feel sure she had not time to feed young. Left nest after a minute. Reappeared for a second then left nest again returned to feed young. I left at this time. June 2, 1942 Arrived at nest about 7:50 a.m. and saw that bird was off the nest. She appeared at 7:54 and flew directly onto the nest, without feeding young. Faced N.E. (I was sitting somewhere N.E. of her). Left nest after about 5 minutes. Gone 8 min. — Flew directly into nest upon her return—did not feed her young. Faced N.E. again. Weather here cloudy and rather cold now. Sun set up her right. Left after about 10 min. I returned in 2 min. To feed young. Fed first one & then the other; each was fed three times. Alight again onto nest on which she stayed barely a minute & then she flew off to the S.W. Faced S.E. while on shortest this time.
