Calliope Hummingbird E. Hole Deep Creek, Kings Canyon, Fresno Co., Calif. May 28, 1942 The hummingbird sat quietly on the nest for ten or fifteen minutes. Close when I got up to get out of the sun somewhat. Was gone for a minute or so and, upon her return, perched on the edge of the nest, same side as that on which she always gets in, & stuck her long beak down into the nest. What the significance of the gesture was, I do not know. After a few seconds of this she settled back onto the nest. The appearance of a bird near the nest, 2:30, caused the hummer to fly out & chase him away. This was a matter of only a second and not a sound was uttered by either bird. I was not able to see the intruder so quickly was he carried over. The Hummer fled immediately back into her nest, & settled down again. She did not circumspectly enter the nest several times before entering as it is herse habit when one are the ones who intrude upon her. The bird was a fairly small one & not a bird of prey. Possibly a Wren? Stayed on nest about ten minutes then flew off heading NE and then circling till she was headed NW. She was back in a very few seconds, could see her head bent
