M. Redon, 1942 Callaope Hemmingbird E Fork Sheep Creek, 5,500 ft., Kings Canyon, Fresno Co. Caly. May 28, 1942 by sound of voices coming down path. Back in about 1/2 minute or less. Un for about 6 minutes and people's voices coming down both of the Hummer was off the nest again for about 10 minute as people passed. Watched cautiously while she left nest & then tried to climb up to see if there was anything in the nest. I could see nothing there, but to she came up to feed the birds which that decided must be in the nest. Then, as the mother came up to her nest, I could see very faintly what appeared to be the round top of a small head. I went down to camp immediately and met J. De May - who suggested that we might be able to see within the nest with the aid of a mirror. We rushed to camp & found a mirror which we took up with us. With a little maneuvering, we saw inside the nest (mother Hummer fluttering about cautiously). There were 2 tiny birds beings wit bright orange beaks, quite short, and wide open mouths. We could find no skull fragments on the ground.
